A battery with emf e = 24 V has internal resistance r = 0.02 S. A load resistor R = 140 S is connected to the terminals of a battery: (i) Find the current flowing in the circuit under load conditions. (ii) Find the terminal voltage of the battery under load conditions. (iii) Find the power dissipated in the resistor R and in the battery's internal resistance r. (iv) Find the open circuit voltage of the battery under no load conditions and explain your answer.

Solution:
A battery with emf e = 24 V has internal resistance r = 0.02 S. A load resistor
