Terminal Potnetial Drop vs Electromotive Force

Question

Question:

While discharging, which is usually greater, the Terminal Potential Difference (TPD)/Terminal Voltage or electromotive force (emf)?

When can the reverse case of the question above be true?

I reposted it to have fresh answers.

Answer 1

While discharging, terminal potential difference is LESS than electromotive force of battery.

While charging the battery, terminal potential difference is MORE than electromotive force.

Answer 2

While discharging, terminal potential difference is LESS than electromotive force of battery.

While charging the battery, terminal potential difference is MORE than electromotive force.

akin na lang 10 points ellaine hehe
