Question

A 9pF parallel plate capacitor has a potential difference of 120V between its plates. The distance between the plate is d= 2mm. What's the potential energy stored in the capacitor ? Please if you need to draw do it. Try to give me a good explanation ... I'm really lost thanks A 9pF parallel plate capacitor has a potential difference of 120V between its plates.

Explanation / Answer

U = 0.5 cV^2 = 0.5 ( 9 x 10^-9) ( 120)^2= 6.48 x 10^-5 J
