Is emf always less than PD True or false?

Is emf always less than PD True or false?
Answer : False. The electromotive force (emf) is not always less than the potential difference (PD). In an ideal situation (such as in a perfect battery with no internal resistance), the emf and the potential difference ... ), the PD equals the emf. But when current flows, the PD can be less than the emf....
