If a current of 1.5 A is maintained in a resistor of 10 2, then the energy dissipated in the resistor in 1 minute will be : (1) 15 W (2) 22.5 W (3) 135 W (4) 1350 W
(4) 1350 W Explanation: The potential difference or voltage, V, across two points is defined as the energy, E dissipated or transferred by a coulomb of charge 9, that moves through two points.
