Where do the electrons go?

Electrons always exist in the circuit as part of the atoms and molecules that make up the circuit. The electrical energy that is delivered is the result of the electrons moving through the circuit. Turn off the pump (i.e. disconnect the battery), and the electrons stop moving through the circuit.

Where do electrons return to?

An atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption. The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed.

What happens to electrons to make electricity happen?

Some electrons around each atom can move around freely and jump from one atom to the next. These electrons make the electrical current happen. When a battery is inserted in a circuit or a lamp is switched on, the electron moves forward but immediately gets hit by the next atom and is deflected.

How do electrons travel?

When a negative charge is brought near one end of a conductor electrons are repelled. When electric voltage is applied, an electric field within the metal triggers the movement of the electrons, making them shift from one end to another end of the conductor. Electrons will move toward the positive side.

Where do electrons go after ground?

Electrons move first one way, then the other, transferring energy to the device whichever way they are moving. Thus, electrons never actually go anywhere, but energy is still used to move the electrons in the wire, and that energy originates at the power plant and is used in the device.

Where do electrons come from in a circuit?

As mentioned above, charge carriers in the wires of electric circuits are electrons. These electrons are simply supplied by the atoms of copper (or whatever material the wire is made of) within the metal wire.

Where does the flow of electrons start?

Electrons flow from the negative terminal to the positive. Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative.

What is it called when electrons flow through a circuit?

If both ends of a piece of wire are connected to the two ends of a battery (called the electrodes), the loop that was made is called an electrical circuit. Electrons will flow around and around the circuit as long as the battery is making an electric field inside the wire. This flow of electrons around the circuit is called electric current.

Where does the energy come from to power the electrons?

The energy to get the electrons moving in an organised way comes from either a battery or a generator. When a battery organises electrons they all move in the same direction at the same time — the battery pumps electrons through the circuit wires from the negative terminal to the positive.

How do electrons move in a power plant?

The electricity generators at power stations organise electrons in a slightly different way. They pump electrons, but they change the direction they’re pumping them 100 times every second. So instead of moving along in one direction like in a DC circuit, the electrons stay pretty much where they are and constantly jiggle forwards and backwards.

What happens when electrons move in synch?

When electrons are forced to move in synch, they can produce heat and — way more impressive — they turn the wire they’re moving in into a magnet. Heat can boil water and make light bulbs glow, and magnets can make things move.
