For other uses, see Volt (disambiguation). The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.
Capital letters are also used as abbreviations for voltage and current. strictly speaking E (for emf) is the correct symbol for a voltage source, with V (for volts) in other parts of the circuit. Vs can be used instead of E for a sourse voltage. The capital letter I is used for current.
