- Work done (W) = charge (q) × potential difference (V). - Charge of an electron = 1.6 × 10⁻¹⁹ C. - Units: Work done in Joules (J), charge in Coulombs (C), potential difference in Volts (V).
The magnitude of work done in moving an electron across two points having a potential difference 6 V is (electronic charge = 1.6 × 10⁻¹⁹ C)
