  • How do electrons travel through a wire?

  • This is how electrons can travel through a wire even if you bend it 90 degrees like a square. In fact, electrons on the surface of the wire are what force other electrons inside the metal to flow.

  • How does electron flow work?

  • (Your lights will light up regardless of the direction of the electron flow.) A lot of people think of electron flow as electrons moving along a wire freely like cars go down a highway. Actually, it works a little differently. Any conductor (thing that electricity can go through) is made of atoms. Each atom has electrons in it.

  • How does a wave travel through a circuit?

  • Each person in the chain moves and contributes to the wave passing through, but nobody actually has to leave their place. Similarly, the electrons are moving and passing on energy to their neighbours which causes a current to flow.

  • What causes a current to flow through a wire?

  • Similarly, the electrons are moving and passing on energy to their neighbours which causes a current to flow. In a metal wire, the electrons creating the current are not tightly bound to the atom, they鈥檙e known as free electrons.
