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 N 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 O.
