Impedance and Complex Impedance
However, reactance in the form of inductive reactance, (X L) or capacitive reactance, (X C) does change with frequency, causing a circuits impedance value to vary as the supply frequency varies. It is for this reason that the expressions of "resistive impedance" (for resistors) and "reactive impedance" (for inductors and capacitors) are sometimes used in …

A capacitor is a device that can store electric charge on its conductive plates. The amount of charge (Q) that a capacitor can store depends on the voltage difference between its plates. When a capacitor is connected to an alternating current (AC) circuit, its capacitance affects how well it can store and release charge as […]
