Inductive reactance XL = 2 · π · f · L
Capacitive reactance XC = 1 / (2 · π · f · C)
Resonant frequency f0 = 1 / (2 · π ·√(L · C))

Apparent resistance (impedance):
|Impedance Z = √ (electrical reactance X)² + (effective resistance R)².
Apparent power S = √ (reactive Q2 + real power P2).
|Real power P in watts
Reactive Power Q in volt-amps reactive (VAR)
Apparent power (complex power) S in (VA) volt-amps
S = √ (Q² + P²) = √ (reactive power²+ real power²)
