Options

  1. AII is increasing QQ is increasing
  2. BII is increasing QQ is decreasing
  3. CII is decreasing QQ is increasing
  4. DII is decreasing and QQ is decreasing

Correct answer

C. II is decreasing QQ is increasing

Step-by-step solution

As clearly ‘QQ’ is increasing so electric field energy in capacitor must be increasing. And hence, magnetic field energy in inductor must be decreasing. So II is decreasing.
