Impedance is measured in which unit?

Explanation:
Impedance is the opposition a circuit offers to alternating current, combining resistance and reactance. Its unit is the ohm (Ω). An ohm is defined as one volt per ampere, so the magnitude of impedance is V divided by I, expressed in ohms. In contrast, volts measure voltage, watts measure power, and amperes measure current. In AC circuits, impedance is a complex quantity Z = R + jX, but its magnitude is still read in ohms.
