The resistance wire AB in the balancing setup shown in figure-`3.292` is 10 cm long. When `AC= 40 cm`, no deflection occurs in the galvanometer. Find the unknown resistance R.

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

The metre bridge wire AB shown in the adjoin figure is 100 cm long when AD = 30 cm, no deflection occurs in the galvanometer. The value of R is

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 40 cm long. Where should the free end of the galvanometer be connected on AB so that the galvanometer may show zero deflection?

In the below circuit , AB is a wire of length 100 cm with 5Omega resistance . If there is no deflection in the galvanometer , the current flowing in the wire AB is

Statement I: In the meter bridge experiment shown in figure, the balance length AC corresponding to null deflection of the galvanometer is x. If the radius of the wire AB is doubled, the balanced length becomes 4x. Statement II: The resistance of a wire is inversely proportional to the square of its radius.
