The amount of energy stored in a capacitor depends on its capacitance, measured in farads, and the voltage across it. The formula for calculating the energy stored in a capacitor is: E = (1/2) x C x V^2. Where E is the energy stored in joules, C is the capacitance in farads, and V is the voltage across the capacitor in volts.
