When internal resistance of the cell can be neglected?

Internal resistance of a cell depends on

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

A dry cell delivering 2 A a terminal voltage is 1.41V. What is the internal resistance of the cell if its open- circuit voltage is 1.59V?

What is called as internal resistance of the cell ?

Power transfer by a non-ideal cell to an external resistor can be same for two different values. Out of which on value (R_(1)) is less than internal resistance of cell and another (R_(2)) is greater than internal resistance of cell then:

Assertion: Terminal potential difference of a cell is always less than its emf. Reason: Potential drop on internal resistance of cell increases terminal potential difference.

The n rows each containinig m cells in series are joined parallel. Maximum current is taken from this combination across jan external resistance of 3 Omega resistance. If the total number of cells used are 24 and internal resistance of each cell is 0.5 Omega then

Explain method to measure internal resistance of cell by using potentiometer.

Write equation to measure internal resistance of cell by using potentiometer.

show a 2.0V potentiometer used for the determination of internal resistance of a 1.5V cell. The balance point of the cell in open circuit is 76.3 cm. When a resistor of 9.5Omega is used in the external circuit of the cell, the balance point shifts to 64.8 cm length of the potentiometer wire. Determine the internal resistance of the cell.
