In a meter bridge the resistance R and x, R being less than x. A balance point is obtained 40 cm from zero and on shunting the coil by `50Omega` the balance point moves through 10cm. Calculate the value of R and x.

Specific resistance of the material of a wire is 44 x 10^6 Omega cm. If the resistance of the wire is 14 Omega and its diameter 1 mm, calculate the length of the wire.

The resistance in two gaps of a meter bridge are 10 Omega and 30 Omega respectively. If the resistances are interchanged the balance point shifts by

In the meter bridge shown in the above figure, the null point is found at a distance 33.7 cm from A and of the wire for particular values of R and S. If a resistance of 12Omega is connected parallel with S, the null point is found to be at 48.1 cm from B end. Determine the value of R and S.

In a Wheatstone bridge the ratio arm P and Q are approximately equal. When R = 500Omega the bridge is balanced. On interchanging P and Q the value of R is 505Omega . Calculate the value of S.

In a metre bridge, the balancing length from the left end is 20 cm. The resistance in the right gap is 1 Omega . The value of the unknown resistance is

In a potentiometer experiment, it is found that no current passes through the galvanometer, when the terminals of a cell are connected across 50 cm of the potentiometer wire. If the cell is shunted by a resistance of 5 ohm, the balance point is found at 40 cm of the wire from the same end. Find the internal resistance of the cell.
