AC Voltage in an Inductor. When a sinusoidal voltage is applied to an inductor, the voltage leads the current by one-fourth of a cycle, or by a 90∘ 90 ∘ phase angle. Current lags behind voltage, since inductors oppose change in current. Changing current induces a back emf V = −L(ΔI /Δt) V = − L ( Δ I / Δ t).
