Consider the following circuit. By keeping S₁ closed, the capacitor is fully charged and then S₁ is opened and S₂ is closed, then

Options

  1. AAt time t=0 , the energy stored in the circuit is purely in the form of magnetic energy.
  2. BAt t 0 , there is no exchange of energy between L and C .
  3. CAt any time t 0 , the current in the circuit is in the same direction.
  4. DAt any time t 0 , the instantaneous current in the circuit may be V c L

Correct answer

D. At any time t 0 , the instantaneous current in the circuit may be V c L

Step-by-step solution
