What is the phase angle between the voltage across and the current through a series RLC circuit if XC is 25 ohms, R is 100 ohms, and XL is 75 ohms?
Answer27 degrees with the voltage leading the current
Net reactance is 75 - 25 = +50 ohms. arctan(50/100) is about +27 degrees, so voltage leads current by about 27 degrees.
