O A thin uniform wire AB of length 1m an unknown resistance X and a resistance of 12 2 are connected by thick conducting strips as shown in figure A battery and a galvanometer with a sliding jockey connected to it are also available Connections are to be made to measure the unknown resistance X using the principle of Wheatstone bridge After appropriate connections are made it is found that no deflection takes place in the galvanometer when the sliding jockey touches the wire at a distance of 60 cm from A Obtain the value of resistance X A X www un C B
