उत्तर
The work done in moving a unit positive charge across two points in an electric circuit is a measure of electric potential difference.
Explanation:
Potential difference is defined as the work done per unit positive charge between two points. Current is the rate of flow of charge, not work per unit charge. Resistance and power are different quantities.
