How does a capacitor store energy? Energy in Electric Field
A: The energy stored in a capacitor is half the product of the capacitance and the square of the voltage, as given by the formula E = ½CV². This is because the energy stored is proportional to the work done to charge the capacitor, which is equal to half the product of the charge and voltage.
