Question

In what condition if terminal potential difference is equal to emf of cell

Answer 1

Explanation:

emf is the max . potential difference between two electrodesoof the cel when terminal is open whereas terminal potential is the potential difference between two electrodes of cell when it is closed.V=E-Ir, where I is internal resistance of cell.✌

Answer 2

Answer:

Explanation:

emf (E) is the maximum potential difference between two electrodes of the cell when the circuit is open and terminal voltage (V) is the potential difference between two electrodes of the cell when the circuit is closed. V=E-Ir, where r is the internal resistance of the cell.
