The capacitor discharge formula is fundamental for calculating how voltage across a capacitor decreases over time. The formula is expressed as V(t) = V₀ * e^(-t/RC), where V(t) is the voltage at time t, V₀ represents the initial voltage, R stands for resistance, C is the capacitance, and e is the base of the natural logarithm.
The formula is the rated fundamental wave capacity of the capacitor. The actual capacity of the capacitor is based on the output capacity when changing 400V to the actual voltage. There is a certain difference between the actual capacity and the rated capacity, because the actual voltage cannot be exactly 400V.
