Voltage/Current Phase Angle “ELI the ICE man” Phil Sherrod – W4PHS When an AC current flows through a resistor, the voltage and current are in phase. However, when you introduce inductance or capacitance, a phase shift occurs and the phase angle depends on the amount of inductive and capacative reactance.

often also interesting, useful, and/or necessary to calculate the Group Delay from this complex vector. Phase is somewhat difficult to handle because of the uncertainty due to the "wrapping" nature of the phase (modulo 360°). Before trying to find the delay (both the phase delay and the group delay) it is important that the phase is "unwrapped".
