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?

Explanation

Net reactance is the inductive reactance minus the capacitive reactance, here 250 Ω − 500 Ω = −250 Ω, so the circuit is net capacitive. The arctangent of −250/1000 is about −14°, and in a capacitive circuit the current leads, which is the same as saying the voltage lags.
