網頁In the circuit shown, a battery of negligible internal resistance is connected in series with a pair of fixed resistors R1 and R2. The circuit is to be used to test whether the electromotive force (e.m.f.) of a particular cell is 1.5 V. The cell is connected between terminals X and Y in parallel with R2 and in series with a galvanometer. 網頁A cell of e.m.f E and internal resistance r is connected across a resistance r. The potential difference between the terminals of the cell must be A E B E/2 C 3E/4 D 3E Medium …
