Electrical impedance - Wikipedia
https://en.wikipedia.org/wiki/Electrical_impedance
Impedance extends the concept of resistance to alternating current (AC) circuits, and possesses both magnitude and phase, unlike resistance, which has only magnitude. Impedance can be represented as a complex number, with the same units as resistance, for which the SI unit is the ohm ( Ω ). See more
