Two coils are connected in series in one gap of a meter bridge and the null point is obtained in the middle of the wire by putting 75 ohm in the other gap. Two coils are then connected in parallel and the null point is obtained again in the middle of the wire, the resistance in the other gap is changed by 57 ohm. Find the resistance of each coil.
