The potentiometer wire AB shown in figure is 40 cm long. Where should the free end of the galvanometer be connected on AB so that the galvanometer may show zero deflection?

The potentiometer wire AB shown in figure is 40 cm long. Where the free end of the galvanometer should be connected on AB so that the galvanometer may show zero deflection?

A uniform wire AB of length 1 m, an unknown resistance X and a resistance of 12 Omega are connected to a battery and a galvanometer G as shown in the figure. The galvanometer shows no deflection when AJ=60 cm. What is the value of X (in ohm) ?

The potentiometer wire AB is 600cm long. At what distance (in cm) from A should the jockey J touch the wire to get zero deflection in the galvanometer?

A secondary cell of emf 2 V and finternal resistance 0.1 Omega is connected to the ends of a uniform wire of length 1 m and resistacne 12 Omega .A primary cell of emf 1.5 V in series with a galvancometer is connected to two points on the wire. If the galvanometer shows no deflection find the distance between the points.
