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. C. Solar Cells 1.
Solar cells are thick pieces of silicon.
When light hits the silicon pieces an electric current is produced. Satellites and telephone companies use solar energy. In order to provide communities with electric power, electricity must be measured. A. Voltage is the unit of measure used to determine the amount of pressure needed to push electrons through a circuit. Examples of electric pressure a.
