    Impedance of a Capacitor Resistor Circuit
    Z = √(XC2 + R2)
    θ = tan-1(-XC/R) = tan-1(-VC/VR)
    The Capacitor Reactance is 90° behind the Resistance
    The Capacitor Voltage is 90° behind the Resistor Voltage


    Impedance of a Inductor Resistor Circuit
    Z = √(XL2 + R2)
    θ = tan-1(XL/R) = tan-1(VL/VR)
    The Inductor Reactance is 90° ahead of the Resistance
    The Inductor Voltage is 90° ahead of the Resistor Voltage


    Impedance of a RCL Circuit
    Z = √((XL - XC)2+ R2)
    θ = tan-1((XL - XC)/R) = tan-1((VL - VC)/VR)
