The force or pressure that causes electricity to flow, measured in volts. Voltage is also called Electromotive Force (EMF) and is cause by the potential difference in voltage from one end of a circuit to the other. With 120 volts at a circuit breaker and 0 volts at a light fixture, flipping a switch will cause the 120 volts to flow to the 0 volts.
Attach the wires to a new switch connecting the hot source to the bottom terminal and the wire running to the light to the top terminal. On a receptacle the black wire from the source goes on the hot, brass colored screws and the white goes to the neutral, silver colored screws. If there are two sets of wires on a receptacle, keep them in sets using the top terminals for one and the bottom terminals for the other set.
Electricity that is flowing from one place to another is called current. The volume of electrical current is measured in amperes or amps.
