In the LC circuit shown below, the current is in direction as shown and the charges on the capacitor plates have the sign as shown. At this instant

Options

  1. AI is increasing Q is increasing
  2. BI is increasing Q is decreasing
  3. CI is decreasing Q is increasing
  4. DI is decreasing and Q is decreasing

Correct answer

C. I is decreasing Q is increasing

Step-by-step solution

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