In the given circuit, when S₁ is closed, the capacitor C gets full charged. Then S₁ is kept open and S₂ is closed. Hence
Options
- AThe current in the circuit is in the same direction.
- BThe instantaneous current in the circuit may be V C L .
- CThe energy stored in the circuit is purely in the form of magnetic energy.
- DThere is no exchange of energy between inductor L and capacitor C .
Correct answer
B. The instantaneous current in the circuit may be V C L .
Step-by-step solution
When S₁ is closed, potential difference across capacitor is V . Direction of current gets reversed when S₂ is closed. When S₁ is opened and S₂ is closed, aligned & 1 2 C V^2= 1 2 L I^2 & I=V C L aligned Total energy oscillates between capacitor and inductor.
