In an experiment with potentiometer to measure the internal resistance of a cell when the cell is shunted by `5Omega` the null point is obtained at 2m .When the cell is shunted by `10Omega` the null point is obtained at 3m .The internal resistance of the cell is

In an experiment with a potentiometer to measure the internal resistance of a cell. when the cell in the secondary circuit is by shounted by 5 Omega , the null point is at 220 cm . When the cell is shunted by 20 Omega the null point is at 300 cm . Find the internal resistance of the cell.

The internal resistance of a cell by potentiometer is given by

In an experiment to measure the internal resistance of a cell by a potentiometer, it is found that the balance point is at a length of 2 m when the cell is shunted by a 5 Omega resistance and is at a length of 3 m when the cell is shunted by a 10 Omega resistance, the internal resistance of the cell is then

In an experiment to measure the internal resistance of a cell by potentiometer, it is found that the balance point is at a length of 2 m when the cell is shunted by a 4Omega resistance and at 3 m when cell is shunted by a 8Omega resistance. The internal resistance of cell is -

In an experiment to measure the internal resistance of a cell by potentiometer, it is found that the balance point is at a length of 2 m when the cell is shuntedd by a 5 Omega resistance, and is at a length of 3 m when the cell is shunted by a 10 Omega resistance. The internal resistance of the cell is, then

A 2.0 V potentiometer is used to determine the internal resistance of 1.5 V cell. The balance point of the cell in the circuit is 75 cm . When a resistor of 10Omega is connected across cel, the balance point sifts to 60 cm . The internal resistance of the cell is

A 2.0V potentiometer is used to determine the internal resistance ofa I.SY cell. The balance point of the cell in the open circuit is obtained at 75cm. When· a resistor of 10Omega is connected across the cell, the balance point shifts to 60cm. The internal resistance of the cell is:
