Impedance in AC Circuits Formulas

Impedance (Z), in electrical devices, refers to the amount of opposition faced by the direct or alternating current when it passes through a conductor component, circuit, or system. And is denoted by Z. Impedance is usually measured using the Ohm for Electric Resistance. Note that the value of Impedance is always negative.
