The phase angle between voltage and current in a purely inductive circuit is:

A 0°

B 90° (voltage leads current by 90°)

C 180°

D 45°

✓ Correct Answer: Option B

In a pure inductor, current lags voltage by 90°. V = L(di/dt); current is the integral of voltage.

💡 Why is B) the correct answer?

The correct answer to the question "The phase angle between voltage and current in a purely inductive circuit is:" is Option B: 90° (voltage leads current by 90°).

The other options — A) 0°, C) 180°, D) 45° — are incorrect for this FE Exam Prep question. As explained above: In a pure inductor, current lags voltage by 90°. V = L(di/dt); current is the integral of voltage.
