Two cells of emfs approximately 5v and 10v

WebIn circuit arrangement shown two cells supply a current I to a load resistarre R = 9 Ω. One cell has an emf E 1 = 9 V and internal resistance r 1 = 1 Ω and another cell has an emf E 2 = 6 V and internal resistance r 2 = 3 Ω. The current are as shown,then 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.
