Question

In the $L-C$ circuit shown in figure, the current is in direction shown in the figure and charges on the capacitor plates have sign shown in the figure. At this time

• A. i as well as Q are increasing
• B. i as well as Q are decreasing
• C. i is increasing but Q is decreasing
• D. i is decreasing but Q is increasing

Answer 1

Answer: (C)

$\frac{dQ}{dt}=-ve$
$\Rightarrow Q\downarrow$
$\Rightarrow i\uparrow \to$ Total energy constant
