Answer:

A cell of emf 'E' and internal resistance 'r' is connected across a variable load resistor R. Draw the plots of the terminal voltage V versus (i) R and (ii) the current I. It is found that when R = 4 ohm, the current is l A when R is increased to 9 ohm, the current reduces to 0.5 A. Find the values of the emf E and internal resistance r.
