RCL Phase Relationships





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
