    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.
