In an experiment with a potentiometer, the null point is obtained at a distance of `60 cm` along
the wire from the common terminal with a leclanche cell. When a shunt resistance of `1 Omega` is
connected across the cell, the null point shifts to a distance of `30 cm` from the common terminal. what is the
internal resistance of the cell?

In the meterbridge experimental set up, shown the null point D is obtained at a distance of 40 cm from end A of the meter bridge wire if a resistance of 10 Omega is connected in series with R_(1) , null point is obtained at AD = 30 cm

When a resistor of 5 Omega is connected across a cell, its terminal potential differnce is balanced by 140 cm of potentiometer wire and when a resistance of 8 Omega is connected across the cell, the terminal potential difference is balanced by 160 cm of the potentiometer wire. Find the internal resistance of the cell.

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:

In a potentiometer experiment the balancing length with a cell is 560 cm. When an external resistance of 10Omega is connected in parallel to the cell, the balancing length changes by 60 cm. Find the internal resistance of the cell.

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

The e.m.f. of a standard cell balances across 150 cm length of a wire of potentiometer. When a resistance of 2Omega is connected as a shunt with the cell, the balance point is obtained at 100cm . The internal resistance of the cell is

The figure Shows the experimental set up of a meter bridge. The null point is found to be 60 cm away from the end A with X and Y in positions as shown. When a resistance of 15 Omega is connected in series with Y, the null points is found to shift by 10 cm towards the end A of the wire. Find the position of the null point if resistance of 30 Omega were connected in parallel with Y.

In a potentiometer experiment , the balancing length for a cell was found to the 1.20 M . Now , a resistance of 10 Omega is connected across the terminals of this cell and the balancing length becomes 80 cm . The internal resistance of this cell is .
