It is an oxidation/reduction reaction. Electrons flow from anode to cathode.
What else can I help you with?
Does the same electron move in the whole circuit?
No, electrons move in a circuit in a continuous flow called an electric current. Electrons move from the negative terminal of the battery, through the circuit components, and return to the positive terminal. Each electron only moves a short distance within the circuit before passing its energy to the next electron.
Does a battery supply the electrons in an electric circuit?
No, is it incorrect to say that a battery produces the charges that circulate in a circuit. Some might suggest that a battery is a current source, but the battery should most properly be considered a voltage source. It generates the electromotive force (emf or voltage) that causes charges to move. (It does this through electrochemical reactions.) The charges that circulate in a circuit (which might be termed the current flow) are already in the conductor and components. All the battery does is produce the voltage (the force) to move charges. Let's look at current flow and see why things might be best looked at in the manner we've stated.Note that the way a battery moves charges is to "inject" an electron into the circuit where it is tied to the negative terminal of that battery. The electron causes one electron in the circuit at the terminal to "move over" and that will cause another electron to "move over" and so on. This will continue until the "last electron" in the circuit at the positive terminal of the battery leaves the circuit and "goes into" the battery. Current flow in the circuit is like musical chairs with electrons everywhere in the circuit "moving over a space" to cause the current flow.Having gone through all that, it should be easier to see why a battery probably should not be considered the producer of charges that circulate in a circuit. Rather, the battery is the source of the voltage that drives the charges (the current) in the circuit.
How does a battery cause electrons to move through an electric circuit?
A battery creates an electric field within the circuit, which applies a force on the electrons, causing them to move. This movement of electrons creates an electric current that flows through the circuit, allowing electrical devices to function.
How a battery causes electron to move in a circuit?
It is an oxidation/reduction reaction. Electrons flow from anode to cathode.
What do Electrons move in a circuit and have millions of?
Electron cloud i think.
What supplies energy to move through a circuit?
A battery
What supplys energy to move electricity through a circuit?
A battery supplies energy to move electricity through a circuit (Remember, a circuit is a wire.)
What happens to a bulb when you move it to the battery on a circuit?
It doesn't matter where the bulb is in respect to the battery, as long as the circuit is complete, the bulb will light up.
Do electrons from a battery reach a bulb before it light?
No, electrons from a battery don't reach the bulb before it lights. An electric current is not simply a flow of electrons. Rather, an electron in a circuit will move only a short distance and then nudge another electron into motion, which will do the same thing with yet another electron. So while the current moves through the entire circuit, individual electrons do not unless it is left on for a very long time.
What happens to a bulb when you move it closer to a battery on a circuit?
The bulb will get brighter
What supplies energy to move elecricity through a circuit?
In a circuit, the energy needed to move electricity is provided by a power source such as a battery or a generator. This power source creates a voltage difference between the circuit's components, which pushes the electric charges to flow through the circuit.
How could you slow down electron flow?
You can slow down electron flow by increasing resistance in the circuit, using resistors for example. By increasing the obstruction to electron flow, you reduce the rate at which electrons can move through the circuit. Additionally, lowering the voltage in the circuit will also slow down electron flow.
