Is electromotive force is the maximum potential difference between the terminals of a battery?

Is electromotive force is the maximum potential difference between the terminals of a battery?
Answer : Yes, electromotive force (EMF) is the maximum potential difference between the terminals of a battery when no current is flowing. It is the voltage generated by the battery or source when it is ... the theoretical maximum voltage the battery can provide under ideal conditions (i.e., no current)....

Under what condition the terminal potential difference across a battery and emf are equal?

Under what condition the terminal potential difference across a battery and emf are equal?
Answer : The terminal potential difference across a battery and its electromotive force (emf) are equal when **no current is flowing through the battery**. This happens when the battery is **open-circuited**, ... a voltage drop, and the terminal potential difference will be less than the emf of the battery....
