    How a Circuit Works!

    A circuit is a loop that lets electrons flow from point A to point B and powering anything in its path.

    A circuit is made out of copper wire (conductor) a device like a light bulb, a switch, and finally a power source like a battery.

    A circuit works from a power source or a battery for example. The power source send electrons through the wire through the device then through the other connected wire, then to the positive side of the battery. Once there are no more electrons in the negative end and they’re all in the positive end there will be no more electricity. A battery holds its charge because electrons are held back by an insulator (something that electricity can’t flow through easily).

    Circuits are used at home, school, anywhere electricity can be used. Parrell circuits are if I turn off one light it doesn’t affect with other light (so the other lights stay on) but on the other hand series circuits are if you turn off one light all lights go out for example a Christmas tree.
    FUN FACTS

    Electricity can travel 7 times around the world a second so imagine the whole world being on a series circuit like if I turn off my light everybody’s lights turn off (*turns off lights “OH NO THE LIGHTS TURNED OFF!”)

    How a Circuit Works

    A circuit is a loop of wire, electrons travel through the wire to power on the source like a light bulb.
    Firstly, a circuit has light bulbs which are in devices, the screen light. It also has batteries, batteries are a portable source of power. They are put into devices and anything that does not need a wire. Circuit’s also have switches to turn off and on, for control. They also have copper wires for the electricity to travel to different locations.
    A circuit works when a loop of wire is connected to a power source. In a circuit, electrons flow from the negative to the positive. In a battery, the anode (negative) flows from the bottom to the cathode (positive) when it does this it powers on the light. When a battery dies the anode doesn’t flow to the cathode any more.
    There are two types of circuits. A series circuit powers on all lights at once. They use a series circuit in a Christmas tree, a series circuit is a regular circuit. Parallel circuits are used everywhere for their own power. Parallel circuits do not turn off all lights like a series circuit would do.
    Finally, electricity can go around the world seven times if it’s powered on, only source of power, mostly light.

    How a Circuit Works.
    Circuits are basically electricity going through wires that power stuff. Circuits are used in our everyday life.
    The stuff that is used to make a circuit is the trigger, like a light switch or a button, the thing that you want to power, a wire and a battery.
    This paragraph will show you how a circuit works. Inside a battery, the bottom of the battery contains electrons that are the batteries power source. The electrons want to go to the top of the battery but the path is blocked. When a battery is put into a toy, a wire is connected to the battery which allows the electrons to go to the top of the battery. When this happens, the electrons power the toy before entering the top of the battery. When the battery runs out of electrons, the battery dies. A series circuit requires a battery that contains more electrons and more stuff that you want to power. Say, a Christmas tree is using a series circuit. If one of the Christmas lights are not working, all of them go off. When electrons go through a Christmas light, it also keeps going to power the other lights. The reason why if one Christmas light goes off, the others turn off to are because when electrons can’t travel through the wire, the flow of electricity is disturbed causing the electrons to not know where to go.
    Series circuits are used in Christmas trees, lights, schools homes, and lots of other places. In a gym, there are several series circuits. There are also several light switches. If you flick one light switch, only some of the lights will turn on. You will need more triggers for more circuits.
    Here are some interesting facts about circuits. The time that it takes for electrons to power something, is light speed. iPhones have tiny little rechargeable batteries. When you put a wire in to charge your Iphone, electrons come through the wire and into the iPhone. It then goes to the rechargable battery, which powers the battery, which powers the iPhone.

    Circuits!

    Circuits are used for electricity to travel and are circular like a loop that just keeps going around. It’s like this endless loop of electricity that powers devices.

    Firstly a circuit has some parts to it. It has a battery or two and it has a light bulb or two like a series circuit which has 2 light bulbs. Circuits also have wires to connect each things together by things it means the light bulb and the batteries and also a switch. The switch is used to turn the light on and off when ever you need or want to obviously. So it’s like a light in your room or anywhere in your house or anywhere really.

    Secondly a circuit works by electrons flowing from the negative end to the positive end. Then when the energy gets around to the light bulb it makes it go on and then the switch makes the light go on and off. When you charge your device or something you want to charge. The electrons go from the anode to the cathode in the battery which is negative to the positive.

    Lastly the series circuits are applied to Christmas lights, lights, doorbells, and anything electrical. Also the parallel circuit goes in the house, school, almost anywhere you can think of that’s electrical.

    There’s all different things in the world that are electrical like the electric eel but there’s a lot of cool interesting facts like series circuits were formally used for lighting multiple unit trains and electricity can go around the world 7 times in 1 second.

    How Does an Electrical Circuit Work?

    An electrical circuit is a loop where electricity travels to power our everyday, modern devices.

    A circuit consists of batteries, or a source of electricity, wires, a light bulb or a device that requires electricity to work, and a switch or something to turn on and off the circuit. A dry cell battery consists of an anode that holds the electrons, an electrolyte that holds the neutrons, and the cathode that has the protons. The wires are usually made of a copper inside, to act as a conductor, and a rubber or plastic outside to act as an insulator and to make sure no electricity can escape the wires.

    When using an electric circuit that has a dry cell battery and a light bulb, the electrons from the anode of the battery travel through the wires to power the light bulb. After that set of electrons are finished the loop of traveling through the wires, they go to the positive end of the battery called the cathode. The electrons stay there and once all of the electrons have traveled through the wires and are now in the cathode, that is how a battery loses all of its power or in other words, it dies.

    Say if you were riding in a multiple unit train a long time ago and someone turned off the light in their room or bunker. Back then the trains ran on a series circuit, and if one person turned off a light, all the lights would go out. Now a day we have developed a new type of circuit called a parallel circuit. A parallel circuit is most of the time used in larger structures or if a group of people or a building wants to have individual uses of electricity. Parallel circuits are found in schools, houses, offices, or any other large buildings.

    Did you know that electricity can travel around the world 7 times in one second? Also, in a blink of an eye electricity can travel half way around the world! As you can see without electricity the world would never be the same. (Congratulations to Benjamin Franklin!)

    How The Circuit works
    A circuit is a loop for the electron that travels and is powered by a battery.
    A circuit is made of several parts. Here are some of the parts, there are light-bulbs, are a source of electricity that can be turned off and on by a switch, also batteries are source of electricity to.
    A circuit works through a loop of wire connected to a power source such as a battery. In the circuit edections move around from the negative end to the positive end. We can use the circuit to power phones, oven, lights and electric cars. Also if we didn’t have electricity or circuits we can’t do much because we need light and ovens to cook.
    Imagine how hard it would be if you turn off one light and all the lights in the house, school, work would turn off well that does happen when you have a series circuit, but if you have a parrell circuit, all the lights won’t turn off when turning off one. So it is the opposite off the series circuit. Did you know that electricity can travel around the world seven times in one second. Electricity is the fastest thing in the world, and electricity provides a lot of things like light, stove, and a lot of other things.

    How a Circuit Works

    A circuit is a loop of wire, through which electrons flow to make a device [light bulb] work.

    A circuit has several parts that it needs to work. There is the light bulb, battery, electrical source, a switch, copper wire, and an insulator.

    A circuit works through a loop of wire that transfers energy from the anode to the cathode. When the electrons travel from the anode to the cathode the electrons go through anything in their way. For example, electrons are going through a wire, and then they come across a light bulb, so the electrons have to pass through the inside, and the light bulb has something inside of it that heats up when the electrons are passing through, and that’s how the light bulb shines.

    Another thing about circuits is that there are two other types of circuits called a series circuit, and a parallel circuit. Series circuits are used in Christmas tree lights and when one of the lights goes out/breaks all the others also go out because there all connected to one circuit and the electrons have nowhere to go. The parallel circuit can be found in houses, schools, street lights, and almost anywhere you go. The way a parallel circuit works is that it is still connected to one circuit but there are several loops that the electrons can use to get around. For example, if a parallel circuit was connected to the whole world, it would let turn individual lights off and still have the rest of them on, as for a series circuit being connected to the whole world, if one light was turned off, all the rest of the lights would turn off because it would be connected to one big circuit.

    Here are some fun facts about electricity. Did you know that in the blink of an eye electricity can circle the world seven times? That’s average to the speed of light!!! Also, you can make electricity by rubbing a in your hair, so if you have a ruler, you can make electricity.

    How a Circuit Works
    An electrical circuit is when electrons travel in a loop. It helps lightbulbs light up for electrical devices to work.
    A circuit consists of batteries, or another electrical source, lightbulbs, wires, and sometimes a switch. Circuits come in different shapes and sizes for it to work properly. Sometimes there are numerous batteries. Sometimes there is only one battery.
    A battery is made up of an anode, electrolyte, and a cathode. The electrolyte doesn’t allow electrons from the anode to flow directly to the cathode. Instead, by hooking it up to a circuit of wires, electrons flow through the wires to the cathode until the anode stops providing electrons. When the electrons travel through a device, it works.
    A series circuit is used most often for Christmas lights. If a Christmas tree light burns out, the entire string becomes inoperable until the bulb is replaced. A parallel circuit is an electrical circuit with two loops connected to each other. It helps light up two lightbulbs.
    Some interesting things about electricity is it can travel around the Earth 7 times in a single second. Also, a classroom has a parallel circuit. Some lights are on, and some lights are off.

    HOW AN ELETRIC CIRCUIT WORKS.
    An electric circuit is a loop of two or more wires, which allows electrons to travel through the loop to power an electrical item.
    Electrical circuits are built up of an electrical source, such as battery’s, the wire, which is usually made of copper, however silver is a better material for this because it’s a better conductor, the switch, which tends to be metal, and an electrical item, such as a light bulb or a tablet.
    Let’s say you want to charge a light bulb with a battery. There are a couple of things you need to do, and learn, to do this. First thing you need to know, is that a battery I made up of three parts. At the top of the battery, you have the cathodes, which are positively charged. In the middle of your battery, you have electrolyte, which has no charge, and at the bottom of your battery, you have anodes, which are negatively charged. You would need to attach your battery to your light bulb with two wires, one per side. This would cause the electrons (negatively charged), to flow from the anode part of your battery to the cathode, because they are both charged differently, and opposites attract. While the electrons flow through the wire, to get to the cathode, they pass through the electrical item that you are attempting to power, causing it to power up. However, if you wanted to add a switch, you would need another wire because one wire would attach the switch to the electrical item, another wire would attach the electrical item to the battery, and another wire would attach the switch to the battery. When you flick the switch up, it disconnects the circuit, because the electrons to no longer flow through, causing your electrical item to turn off. When you flick the switch down, it causes the loop to reconnect, which turns the power back on, because the electrons to flow through.
    There are two types of circuits, a series circuit, and a parallel circuit. A series circuit is a circuit that has only one energy stream. If you turn off one electrical item, they all turn off. An example of a series circuit is an older model of Christmas tree lights. One goes out, they all go out. Another type of circuit is parallel. A parallel circuit allows individual use of light. If one light goes out, only that electrical item goes out. You will see this in houses, and local shops.
    Did you know, energy goes around the world 7 times per second? Also, did you know, lightning strikes 40-50 times per second?
    Energy is an amazing thing. We would not be the same world without it. By:Keira

    How a Circuit Works
    An electrical circuit is a loop where electricity travels to power a device when linking electrical components together.
    An electrical circuit consists of a wire, a battery, a bulb and a switch. Some of the time, silver wire is used because it’s the most powerful conductor yet costs a lot of money, so most of the time the wires are made of copper.
    There are three parts of a dry cell battery to make electricity power devices. There is the cathode which is the positive end. There is the electrolyte which is where everything gets its power, and the anode which is the negative end. The anode (Negative end) makes is way to the cathode (Positive end) while powering the device, but when all the electrons are gone from the negative end, the battery dies.
    In order to make an electrical circuit work, there are four main things you will always need: a switch to turn the device on or off, the device to be powered (Such as a light bulb), and the wires that allow the electrons to get to the device. The battery has two sides: one side is the positive end and the other is the negative end. The electrons flow though a copper or silver wire insulated with rubber, the electrons then make their way through another copper or silver wire towards the switch, then to the positive end.
    An electrical circuit is used multiple times and in two ways. There is a parallel circuit and a series circuit. A parallel circuit has multiple loops. When one light bulb turns off and the other light bulbs stay on. A series circuit is when one light bulb turns off, all the others stay on. In other words, imagine a parallel circuit as a school’s lights. When one light turns off, all the others are still on. A series circuit are like old fashion Christmas lights, not modern day lights. When one light turns off, all the others do too. However, most modern Christmas lights are made with parallel circuits.
    Did you know that electricity can travel around the world 7 times in a second? It’s amazing what electricity can do and how it works! Without electricity, this world would be in chaos! Imagine people driving with only candles!

    How a Circuit Works
    A circuit is a device that makes electricity by a loop of wire.
    Here are some of the circuit parts: light bulbs, batteries, and switch. Batteries are a source of electricity, the wires are made of copper, and the switch is used for powering on and off the light.
    A circuit works through a loop of wire connected to a power source. In the battery the electrons flow from the negative end, through the wire, through the light bulb or anything else that’s getting powered, then it goes to the positive side. When the battery runs out of energy, the thing that’s getting powered stops working.
    Here’s an example of how a series circuit works. On a Christmas tree, when you take out one light, all of the lights will turn off. Here’s another example of how a parallel circuit works. A parallel circuit has multiply loops so if you turn off one switch then only one light will turn off.
    An interesting fact is that electricity can go around the world 7 times in the blink of an eye.

    How a Circuit Works
    A circuit is a series of energy sources that travel through different wires to produce electricity.
    The parts of a circuit are the light bulb, the switch, the wires often made of copper, and the battery or source of electricity.
    The many different parts of a circuit all serve a purpose in the circuit. One of the parts of a circuit is the light bulb. When the energy created travels through the wires and comes across the light bulb, it begins to glow. Another part of the circuit is the switch. The switch is the part of the circuit that turns the circuit on and off. When the switch is turned up, it disconnects the circuit and the energy can no longer flow though. However, if the switch is turned down, it connects the wires together allowing energy to flow through the wires allowing the circuit to produce energy. The next part of a circuit is the battery. In the battery, the electrons travel in a loop from a part of the battery called the Anode, through the wires to the light bulb, to power it. Once the electrons have passed the light bulb, they travel to another part of the battery called to Cathode. Once all the electrons have left the Anode and travelled to the Cathode, the battery itself has lost power. Lastly, the copper wires. The wires are where the energy travels through to get to the light bulb.
    There are circuits everywhere! One of the circuits is called the series circuit. The series circuit is a circuit when all lights and energy sources work together. For example, Christmas tree lights would be a good example of a series circuit. Then there is a parallel circuit. A parallel circuit is if you were to turn one light off in a building, no other lights would go off with that light. Parallel circuits are often found in schools or homes.
    Along with electricity being extremely useful, there are also many in the time you blink your eye, electricity could have travelled around the world 7 times! Another fact about electricity is that and electricity is that an electric eel can reach up to 500 volts of energy! There are so many incredible things to discover about electricity and circuits.

    HOW AN ELECTRICAL CIRCUIT WORKS

    A circuit is a loop of electrons flowing, and it is used to turn devices on/off.

    The parts of a circuit are wires, switches, batteries, or another source of power, light bulbs, and connecter.

    A circuit works when a wire is connected to a power source to power devices such as remote control cars. In a circuit, the electrons flow from the negative end to the positive end of the battery. A parallel circuit has multiple loops. When one light is turned off, the other lights stay on. A series circuit has a single loop. If one light is turned off, all the other lights turn off.

    How a circuit works!
    First, a circuit is a loop that electrons that travel thought weirs to get to the protons or the positive.
    The parts of a circuit are a light bulb, a battery / a source of electricity, alligator clips, and wire.
    A circuit works through a light inside of the wire to power the light with the electrons from goes through the wire and the switch and the light bulb and back to the battery.
    The series circuit is like when one light bulb goes off the rest of them go off. A parallel circuit is when one light bulb goes off but the others don’t go off they keep going.
    Fun Fact: Electricity can travel the earth in ¼ times in 2 seconds.
