a batttery is composed by 120 cells in series. Each element has an emf of 2V and internal resistance of 0.001 Ohms.the combination is connected to an external resistance of 4.8 Ohms. calculate:
a)the intensity of the current in the circuit
b)The voltage at the terminals of the battery
c)the energy dissipated by joule effect when the current flows in the circuit in one hour
