The emf of a cell is always greater than its terminal voltage. Why? Give reason.

The emf of a cell is always greater then its terminal voltage. Why

The emf of a cell working as a source is greater than its terminal voltage. Why?

Assertion: Terminal voltage of a cell is greater than emf of cell during charging of the cell. Reason: The emf of a cell is always greater than its terminal voltage.

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : The e.m.f. of a cell is always greater than the terminal potential difference between its two pole. Reason: There is always some potential drop across the internal resistance of the cell.

Assertion: Terminal voltage of a cell is greater than emf of cell during charging of the cell. Reason: The emf of a cell is always greater than its terminal voltate.
