A capacitor voltage just before switching is 12 V. If no impulsive current is applied at the switching instant, its voltage immediately after switching is?

  • A0 V
  • B6 V
  • C12 V
  • DInfinite
Report an error
Correct Answer: C. 12 V
Explanation: Capacitor voltage cannot change instantaneously without an impulse current, so vC(0+)=vC(0-)=12 V.
Reference: Standard network theory: capacitor continuity
