The formula for energy stored in a capacitor is 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.

Rearranging the formula to solve for V, we get: V = sqrt(2E/C)

Substituting the given values, we get: V = sqrt(2*80*10^-3/100*10^-6) = 40V

Therefore, the answer is D.

To Store 80 MJ of Energy in a 100 μ\muμ F Capacitor,what Voltage Is Necessary? A) 10 V B) 45
