• 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 2m when the cell is shunted by a $5\,\Omega $ resistance; and is at a length of 3m when the cell is shunted by a $10\,\Omega $ resistance. The internal resistance of the cell is, then
