Question: Is electricity a form of energy?

Not really, electricity is a way of transporting energy from one place to another.

The energy is often called electrical energy while it is between the source (i.e. the cell, battery or power supply) and whatever is using the energy (e.g. a bulb).

But this often leads to the incorrect idea that the energy moves around the circuit from cell to bulb.

This leads to further misconceptions such as that there is no energy after the bulb and that it takes time for the energy to reach the bulb because it must travel a distance first.

When there is electricity flowing in a circuit, all the free electrons are moving so energy is all around the circuit.
