⚜Electromotive force:-

1. E.m.f is the energy supplied to the unit charge by the cell.

2. E.m.f is the cause.

3. The E.m.f is also present even when no current is drawn through the battery.

4. It's unit is Volt.

⚜Potential Difference:-

1. Potential difference is the energy dissipated as the unit charge passes through the components.

2. Potential Difference is the effect.

3. Potential Difference across the conductor Is zero in the absence of current.

4. its unit is volt.
