Question

What is the difference between emf and potential difference between the electrodes of a cell?

Answer 1

Answer:

E.m.f is the energy supplied to the unit charge by the cell. Potential difference is the energy dissipated as the unit charge passes through the components.

Answer 2

☆$\red {HELLO\:DEAR}$☆

• If the difference in potential between the 77 of the same cell is measured in a closed circuit, it is termed as potential difference.
• Closed circuit means measurement is carried out under load.
• EMF is the maximum potential available in a galvanic cell.
