Question

define terminal potential difference​

Answer 1

Originally Answered: What do we mean by the potential difference between two terminals? ... The electromotive force (emf) is the potential difference of a source when no current is flowing. Terminal voltage is the voltage output of a device is measured across its terminals. Terminal voltage is calculated by V = emf - Ir.
