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)
