What is the phase angle between the voltage across and the current through a series RLC circuit if XC is 500 ohms, R is 1 kilohm, and XL is 250 ohms?
Pick an answer to check it.
Answer: C. 14.0 degrees with the voltage lagging the current
Net X = XL - XC = 250 - 500 = -250 ohms (capacitive). Angle = arctan(250 / 1000) = 14.0 degrees. Capacitive circuits have voltage lagging current.
Tip: Capacitive: voltage lags (ICE).
