Electricity:

requires a complete path or circuit for electrical energy to flow; the flow of electrical energy is called electric current.

An electrical circuit requires:

• an energy source, such as a battery

• a conducting material, such as a metal wire to carry the electric current

• a receiver or source, such as a light bulb, motor, or buzzer

• a circuit can also have a switch to turn it on and off.
