Another output of the capacitor energy calculator is the capacitor's charge Q Q. We can find the charge stored within the capacitor with this expression: where again: Q Q is the charge within the capacitor, expressed in coulombs. The capacitor energy calculator finds how much energy and charge stores a capacitor of a given capacitance and voltage.
A capacitor's energy (or work) can be calculated using the equation: E = 0.5 * C * V, where E is the energy, C is the capacitance, and V is the voltage. For example, a capacitor with a capacitance of 5 Farads and a voltage of 50 mV would have an energy of 0.125 Joules.
The angle between the total impedance and its complex component is called the ‘loss angle,’ and is a figure used to summarize the ratio between the ideal and non-ideal components of a capacitor’s overall impedance. The tangent of the loss angle is usually provided, which actually simplifies things a bit.
