Three identical cells of e.m.f. `1.5 V` are given. Find how we can arrange them to get a total e.m.f. of
(a) `1.5 V`, (b) `3 V`, (c ) `4.5 V`.

Text Solution

Verified by Experts

(a) When all cells are connected in parallel. The total e.m.f of the combination is 1.5 V. (b) When cells are connected as shown in figure,two of them in series and one in parallel, then the total e.m.f of the combination is 3 V. (c) When all the three cells are connected in series, then the total e.m.f is 4.5 V.
