In pure circuits, the phase difference between voltage and current is definitively π/2 radians. This occurs in circuits consisting solely of capacitors or inductors, without any resistive components. The absence of resistance ensures that the current leads or lags the voltage by exactly 90 degrees, which is a fundamental characteristic of reactive components. Understanding this phase relationship is crucial for analyzing AC circuits effectively.
