In an LCR series circuit, if the AC frequency is increased to a very large value, what value does the magnitude of the angle between the current and voltage phasors approach?
A) 0°
B) 45°
C) 180°
D) 90°

At very high frequencies, the inductive reactance becomes much larger than the capacitive reactance, causing the circuit to behave like a purely inductive circuit. In a purely inductive circuit, the current lags the voltage by 90 degrees.
