Question 17 POST_UTME_IMS_U • 2020 • PHYSICS • objective

A parallel plate capacitor has a capaci\tance of $C = 2 \times 10^{-6} , \text{F}$ and is charged to a potential difference of $V = 10 , \text{V}$. If the plates are then separated by a dis\tance $d = 2 , \text{mm}$, what is the energy stored in the capacitor?

Correct Answer A. $ U = \frac{1}{2}CV^2 $

B. $ U = \frac{1}{2}CV $

C. $ U = \frac{1}{2}CV^2 left\( 1 - \frac{d}{D} \right \ $ )

D. $ U = \frac{1}{2}CV^2 left\( 1 + \frac{d}{D} \right \ $ )

Correct Answer

Correct Option:

$ U = \frac{1}{2}CV^2 $
