Solution:
Statement (A) is correct as EMF is indeed a potential difference under open circuit. Statement (B) is incorrect because during charging, the terminal potential difference is \(V = E + Ir\), which is greater than the EMF \(E\).
Consider the following statements and choose the correct optionnStatement (A): Electromotive force (emf) is not a force, it is the voltage difference between two terminal of a battery in open circuit.nStatement (B): The potential difference across terminals of a battery having some internal resistance can never be greater than the emf of the battery.
