Question

Ex. 37: Two resistance P and Q are connected
in series in one gap of meter bridge. The
balance point is at the centre of the wire, with
resistance 50 in the other gap. If P and Q are
connected in parallel in the same gap, the
known resistance is to be changed to 12 to
obtain the balance point at the centre again.
Calculate the resistance of P and Q.
