Shown in the figure below is a meter- bridge set up will null deflection in the galvanometer.

The value of the unknown resistor R is

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

A meter bridge setup is shown in the figure. If there is null deflection in galvanometer when length AC = 20 cm, then the value of resistance R is

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

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.

STATEMENT-1 : In the meter bridge experimeter 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 balance length becomes 4x. and STATEMENT-2 : The resistance of a wire a inversely proportional to the square of its radius.

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.

In a meter bridge experiment shown below, the null point is obtained at P. The value of unknown resistance X is 2012 50 cm 1.) E
