MCQ Practice Question

An inductor carries 3 A just before switching. If no impulsive voltage is applied, its current immediately after switching is?

  • A0 A
  • B1.5 A
  • C3 A
  • DInfinite
Report an error
Correct Answer: C. 3 A
Explanation: Inductor current is continuous in the absence of an impulse voltage, hence iL(0+)=iL(0-)=3 A.
