Question

what is the unit of impedance ​

Answer 1

Answer:

The unit of impedance usually signified by symbol Z, is the ohm, which relates the voltage required to drive a current of one amp through a resistor, inductor or capacitor. The reactive elements L & C shift the phase relation of voltage and current which can be expressed as a complex number (real, imaginary) or as a phase angle between the voltage taken as the 0 reference, and the resulting current in degrees, There are a number of other ways of conveying this phase difference such as power factor.
