AC Circuits with Resistors, Inductors and Capacitors
Purely Resistive Circuits In resistive elements the current and voltage are in phase. Purely Capacitive Circuits In capacitive circuits, the current leads the voltage by 90°. Purely Inductive Circuits In inductive circuits the current lags the voltage by 90°. Related: Inductance R, L, and C in Series Because the voltages and the currents are not…

Capacitors, Capacitance and Charge
Introduction to Capacitors A capacitor is an electrical device that is used to store electrical energy. A capacitor consists of two metal plates separated by an insulator called a dielectric. It stores electricity in the form of an excess of electrons on one plate and a deficiency on the other. In this state, the capacitor…
