1. The problem statement, all variables and given/known data
A parallel-plate capacitor with C = 16 mu or micro FF is charged so as to contain 1.7 J of energy. If the capacitor has a vacuum between plates that are spaced by 0.35 mm, what is the energy density (the energy per unit volume)?
I am a little lost of this problem and have no idea if I'm doing it correctly. Am I ?
2. Relevant equations
v = A*d
E,density=U/v
3. The attempt at a solution
v=16e-3/.35e-3=45.71
E=1.7/45.71=.0371 J/m^3
