Description

Electricity is described as the flow of electrons, which is named as current. The analogy used is carts racing around a track. Conductors are described as substances which allow electrons to flow through them. Insulators are described as substances in which electrons can't flow. The workings of a light bulb are explained but resistance is not mentioned.
