When a Daniel cell is connected in the secondary circuit of a potentiometer, the balancing length is found to be 540 cm. If the balancing length becomes 500 cm. When the cell is short-circuited with `1Omega`, the internal resistance of the cell is

When 6 identical cells of no internal resistance are connected in series in the secondary circuit of a potential meter, the balancing length is /, balancing length becomes l/3 when some cells are connected wrongly, the number of cells connected wrongly are

When 6 identical cells of no internal resistance are connected in series in the secondarycircuit of a potentio meter, the balancing lengths is .l., balancing length becomes 1/3 when some cells are connected wrongly, the number of cells connected wrongly are

When 6 identical cells of no internal resistance are connected in series in the secondarycircuit of a potentio meter, the balancing lengths is .l., balancing length becomes 1/3 when some cells are connected wrongly, the number of cells connected wrongly are

In a potentiometer the balancing with a cell is at length of 220cm. On shunting the cell with a resistance of 3Omega balance length becomes 130cm. What is the internal resistance of this cell.

In a potentiometer the balancing with a cell is at length of 220cm. On shunting the cell with a resistance of 3Omega balance length becomes 130cm. What is the internal resistance of this cell.

When a resistance of 12 ohm is connected across a cell, its terminal potential difference is balanced by 120 cm length of potentiometer wire. When the resistance of 18 ohm is connected across the same cell, the balancing length is 150 cm. Find the balancing length when the cell is in open circuit. Also calculate the internal resistance of the cell.
