Question

In a purely inductive AC circuit, the current lags the voltage by what phase angle?

Options

Choose one · Correct answer highlighted

0° 45° 90° Correct 180°

Explanation

For a pure inductor, i = i_m sin (omega t - π/2), while v = v_m sin omega t . Phase difference: phi = -π/2, meaning current lags voltage by π/2 or 90° .
