List of top Physics Questions on Wheatstone Bridge

Assertion (A) : In a Wheatstone bridge circuit, if we interchange the position of the cell and the galvanometer, the balance condition \(\frac{P}{Q} = \frac{R}{S}\) remains unchanged.
Reason (R) : \(\frac{P}{Q} = \frac{R}{S} \Rightarrow \frac{P}{R} = \frac{Q}{S}\) so balance condition remains same.
