Series RLC Circuit 
When XL is greater than XC, the phase is positive. | 
When XL is less than XC, the phase is negative | 
When XL = XC the impedance (ZT) is the same as R, and there is no phase angle. | | Procedure Analysis of a series RLC circuit, given the values of VT, XL, XC, and R
Step 1: Calculate the total impedance Step 2 Calculate the total current Step 3 Determine the current for each component IR = IL = IC = IT Step 4 Calculate the voltage for each component - VR = IT x R
- VL = IT x XL
- VC = IT x XC
Step 5 Determine the phase angle for each component and the total phase angle - qR = 0�
- qL = �90�
- qC = 90�

When VL is greater than VC, the phase is positive. | 
When VL is less than VC, the phase is negative | 
When VL = VC the voltage across the resistor (VR) is dental to the source voltage VT) | Voltage phasors for RLC circuits are identical to those for impedance. The special point where where the reactances are equal (and the reactive voltage is zero
