A 0.25-μF capacitor is connected to a 300-V battery.What potential energy is stored in the capacitor? A) 1.2 × 10−³ J B) 3.8 × 10−⁴ J C) 2.25 J D) 0.011 J E) 0.023 J

Question

Quizplus · Accepted Answer

The potential energy stored in a capacitor U can be calculated using the formula U = 0.5 * C * V^2, where C is the capacitance and V is the voltage. Substituting the given values, U = 0.5 * 0.25 x 10^-6 * (300)^2 = 0.011 J. Therefore, the correct choice is D.
