A 12.0- A 12.0- A 12.0-V battery remains connected to a parallel plate capacitor with a plate area of 0.204m^2 and a plate separation of 3.14mm .
What is the charge on the capacitor?
Q = C
How much energy is stored in the capacitor?
Uc = J

What is the electric field between its plates?

E = V/m

  • College Physics -

    Calculate the capacitance (C = eo A/d)
    then
    Q = C V
    and
    energy = .5 Q V = .5 C V^2
    then indeed
    E = V/ spacing in meters between plates.
