In the circuit given below Inductor used is ideal inductor, What is the conduction angle of diode? [Figure description: A series loop of an AC voltage source Vs (left), a diode (in the top wire, conducting left to right), and an ideal inductor (right).]
- A. 90°
- B. 180°
- C. 270°
- D. 360°
Answer: D. 360°
Explanation: For an ideal pure inductor load, current i(t) = (Vm/ωL)(1 − cos ωt) ≥ 0, which only returns to zero at ωt = 2π (360°), so the diode conducts for the entire cycle.
