Vedclass · Answer

(D) The graph shows the variation of voltage $V$ (on the y-axis) with charge $q$ (on the x-axis) for a capacitor.The area under the $V-q$ graph represents the work done in charging the capacitor,which is stored as potential energy.The area of the triangle $AOB$ is given by:$	ext{Area} = \frac{1}{2} 	imes 	ext{base} 	imes 	ext{height}$$	ext{Area} = \frac{1}{2} 	imes q 	imes V$Since the energy stored in a capacitor is $U = \frac{1}{2} qV$,the area of the triangle $AOB$ represents the energy stored by the capacitor.

The charge $q$ on a capacitor varies with voltage $V$ as shown in the figure. The area of the triangle $AOB$ represents:
