Wheatstone Bridge & Metre Bridge

In a Wheatstone's bridge, the resistances in four arms are as shown in the figure. The balancing condition of the bridge is

Show answer and solution

Answer: (d)

$S_1$ and $S_2$ are in parallel: $S = \frac{S_1 S_2}{S_1 + S_2}$
Balance: $\frac{P}{Q} = \frac{R}{S}$
$\frac{P}{Q} = \frac{R(S_1 + S_2)}{S_1 S_2}$
So the answer is (d).
