WebThe RMS current value is I = 15.92 A The RMS voltage value is V = 220 V Therefore, the total power taken can be derived by the following equation: P = VI cos Φ Here, Φ is the phase difference between V and I In the case of a purely inductive circuit, the difference in the phase of an alternating voltage and an alternating current is 90°, WebA capacitor is an electrical device that stores energy. It is a kind of battery that is used to store power. It is a two-terminal passive electrical component that is used in circuits. Capacitance is the technical name for the capacitor’s effect. When a capacitor is connected to a voltage source, it draws current to charge the capacitor.
