Energy stored in the capacitor

Vedclass · Answer

(D) The energy stored in a capacitor is given by the formula $U = \frac{1}{2}QV$.In the given graph,$Q$ is plotted on the $X$-axis and $V$ is plotted on the $Y$-axis.The area of the triangle $OAB$ is given by $	ext{Area} = \frac{1}{2} 	imes 	ext{base} 	imes 	ext{height}$.Here,the base is $OB = Q$ and the height is $AB = V$.Therefore,$	ext{Area} = \frac{1}{2} 	imes Q 	imes V = \frac{1}{2}QV$.This expression represents the energy stored in the capacitor.

The charge $Q$ on a capacitor varies with voltage $V$ as shown in the figure,where $Q$ is taken along the $X$-axis and $V$ along the $Y$-axis. The area of triangle $OAB$ represents
