Inductive reactance


Capacitive reactance


Impedance in relation to R and X

ZL = R + jXL

ZC = R - jXC

Ohm’s Law for AC


Series and Parallel Impedances

NOTE: All impedances must be calculated in complex number form for these equations to work.



Resonance

NOTE: This equation applies to a non-resistive LC circuit. In circuits containing resistance as well as inductance and capacitance, this equation applies only to series configurations and to parallel configurations where R is very small.
