Question

Differen bw emf and terminal potential differen

Answer 1

Answer:

• The electromotive force is the measure of energy that it gives to each coulomb of charge, whereas the potential difference is the amount of energy used by the one coulomb of charge. ... The potential difference is the measure of energy between any two points on the circuit.

Answer 2

Explanation:

The terminal potential difference of a cell is equal to the emf of the cell when:

→ The cell is an open circuit.

→ The internal resistance of the cell is zero.

→ The load resistance much greater than internal resistance
