When the light is turned on, a complete circuit is created. The light switch acts as a bridge for the electric current to travel through the circuit. Electricity is produced from a power source. A. Batteries 1. A battery contains chemicals that can push electrons from one atom to the next.
Batteries make electrons move in one direction producing a direct current.
B. Generators 1. Generators move electrons by coils of wire and magnets. Generators must contain many wire loops to create electricity. Generators can be found in cars. The bigger the generator the more electricity will be generated.
