Explainer: Understanding electricity

Electricity is the term we use to describe the energy of charged particles. Electricity might be stored, like in a battery. When you connect a battery to a light bulb, electricity flows. This happens because electrical charges ( electrons) are free to carry energy from the battery through the bulb.
