You attach a 30-pF capacitor across a 1.5-V battery.How much energy is stored in the capacitor? A)3.4 $\times$ 10^-11 J B)4.5 $\times$ 10^-11 J C)6.7 $\times$ 10^-11 J D)3.4 $\times$ 10^-8 J E)4.5 $\times$ 10^-8 J

Question

Quizplus · Accepted Answer

The energy stored in a capacitor is given by the equation E = 1/2 * C * V^2, where E is the energy in joules, C is the capacitance in farads, and V is the voltage in volts. Plugging in the given values, we get E = 1/2 * 30 pF * (1.5 V)^2 = 3.4 x 10^-11 J.
