WebGiven two cells of emf approximately 5 V and 10 V are compared. To compare these cells accurately potential drop across potentiometer wire must be slightly greater than that of … WebDec 10, 2024 · The electromotive force (EMF) is the maximum potential difference between two electrodes of a galvanic or voltaic cell. This quantity is related to the tendency for an element, a compound or an ion to acquire (i.e. gain) or release (lose) electrons. For example, the maximum potential between Zn and Cu of a well known cell.
