Charged capacitor

jeudi 30 janvier 2014

1. The problem statement, all variables and given/known data

A voltage of 14 V is placed on a capacitor with C = 113 pF (picofarads).



(a) What is the charge on the capacitor?



(b) How much energy is stored in the capacitor?



I believe I have the correct equation but I'm not sure about the final answer because of the picofarads. Are my answers correct?



2. Relevant equations



(a)Q=C*U

(b)E,stored=1/2*C*U^2



3. The attempt at a solution

(a)113*14=1.582e-6

(b)113*14^2*(1/2)=11.074e-6
