Two coils P and Q are connected in series in one gap of a slide wire bridge and the null point is obtained at midpoint of the wire by putting a resistance of 37 5 2 in the other gap The two coils are then connected in parallel and null point is obtained at the midpoint of the wire by keeping 9 Q in the other gap The resistances of P and Q are A 20 Q and 17 5 9 30 22 and 7 5 Q 22 5 Q and 15 Q 22 Q and 15 5 Q C B D Pvt
