Voltage. Voltage is electric potential energy per unit charge, measured in joules per coulomb (= volts). It is often referred to as electric potential, which then must be distinguished from electric potential energy by noting that the potential is a per-unit-charge quantity.oltage is electric potential energy per unit charge, measured in joules per coulomb (= volts).
voltage. The force, or pressure, of electricity. Also known as potential.. Voltage drop is the difference in voltage from one end of an electrical circuit to the other. For instructional purposes, voltage is often compared to water pressure. See voltage drop, volt-amps and current.he force, or pressure, of electricity. Also known as potential.. Voltage drop is the difference in voltage from one end of an electrical circuit to the other.
