For a cell, a graph is plotted between the potential difference V across the terminals of the cell and the current I drawn the cell. The emf and the internal resistance of the cell are E and r, respectively. Then

For a cell, the graph between the p.d.(V) across the terminals of the cell and the current I drawn from the cell is shown in the fig. the emf and the internal resistance of the cell is E and r respectively.

for a cell, the graph between the p.d. (V) across the terminals of the cell ad te current I drawn from the cell is shown in the fig. the emf and the internal resistance of the cell is E and r respectively.
