Power source - Either electrical or battery, provides the power to the load.

Conducting path - The wires, carry the power from the power source to the load

Load - The device using the electricity such as a computer, light bulb, power saw, etc. More complicated circuits use switches, such as light switches, to control the flow of electricity.
