Final answer:
The phase relationship between voltage and current in an inductive circuit is that the voltage across the inductor leads the current by one-fourth of a cycle or by a 90° phase angle.
Step-by-step explanation:
The phase relationship that exists between the voltage and the current in an inductive circuit can be remembered by the fact that the voltage across the inductor leads the current by one-fourth of a cycle or by a 90° phase angle.
For example, when a sinusoidal voltage is applied to an inductor, the voltage waveform will reach its peak before the current waveform does. This phase relationship can be represented on a phasor diagram, where the voltage phasor rotates ahead of the current phasor by a certain angle.
It is important to note that this phase relationship only applies to inductive circuits, and the relationship may vary for different circuit elements like resistors and capacitors.
