A difference between two points that transfers energy to or from each coulomb of charge, measured in volts (V).
Revise: Electrical charge and currentAn electric circuit needs a closed path and a source of potential difference before charge can flow continuously. A closed circuit is an unbroken conducting loop: an open switch or a disconnected wire breaks the path, so there is no continuous flow around the circuit.
