Two coils are connected in series in one gap of a meter bridge and the null point is obtained in the middle of wire by putting 7 omega 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 gap other gap is changed by 57omega.find the resistance of each coil?
