Question

Wires X and Y of resistances are in the ratio
1 : 2. When the wires are connected in series to a
battery of e.m.f. 2V, as shown in figure, the ratio
of the p.d. across X to the p.d. across Y will be

Answer 1

Explanation:

Pd across X is (I x X)

pd across Y is ( I x Y)

pd (X)/pd(Y) = X/Y

pd (X) / pd(Y) = 1:2
