Impedance is resistance and reactance¶

Impedance is the combination of resistance and reactance (both inductive and capacitive) and is a complex number, containing both real and imaginary parts. The real part of impedance is resistance, and the imaginary part is reactance.

Notation:

\(i\) is the imaginary unit.
