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?

The potentiometer wire AB shown in figure is 50cm long.When AD=30cm, no deflection occurs in the galvanmeter.Find R.

The wire AB of slide wire bridge 68 is 400 cm long. Where should the jockey J whose one end connected to galvanometer,the other end can be connected to AB, so that galvanometer shows no deflection ?

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 potentiometer wire AB as shown in 40 cm long of resistance 50Omega//m free end of an ideal galvanometer is touching the potentiometer wire with the help of a jockey. What should be the velocity of the jockey as a function of time so that potential difference across the galvanometer is varying with time as (2sinpit)V

A potentiometer circuit shown in the figure is set up to measure e.m.f. of a cell E . As the point P moves from X to Y the galvanometer G shows deflection always in one direction, but the deflection decreases continuously until Y is reached. In order to obtain balance point between X and Y it is necessary to

For the potentiometer arrangement shown in the figure, length of wire AB is 100 cm and its resistance is 9 Omega . Find the length AC for which the galvanometer G will show zero deflection.
