  1. noun
    the difference in electrical charge between two points in a circuit expressed in volts
  2. noun
    the rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in volts
Definition that contains voltage
  • earth a connection between an electrical device and a large conducting body, such as the earth (which is taken to be at zero voltage)
