A) During the discharging of battery, the battery supplies electrical energy at the rate of \[VI=EI-{{I}^{2}}r\]. Here, El represent the rate at which non-electrical energy is converted to electrical energy
B) During the charging of battery, the battery consumes energy at the rate of \[VI=EI+{{I}^{2}}r\]. Here, El represents the rate at which electrical energy is converted to non-electrical energy
C) In both the above cases the term \[{{I}^{2}}r\]represents the rate of dissipation of energy in the internal resistance of battery
D) None of the above
Correct Answer: D
Solution :
During discharging, battery supplies electric power to external circuit, while during charging the charger supplies electrical energy to the battery. In both the cases some part of the energy is dissipated as heat in internal resistance of the battery.
