What is impedance of a circuit?

Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. … Impedance is a complex number, with the same units as resistance, for which the SI unit is the ohm (Ω).

How do you calculate impedance of an inductor?

Answer: The inductor impedance calculator calculates the impedance of an inductor based on the value of the inductance, L, of the inductor and the frequency, f, of the signal passing through the inductor, according to the formula, XL= 2πfL.
