Hi,
I was wondering how I would find the electric field strength inside a parallel-plate capacitor. I have been trying to find an equation, but seem to fall short. The electric field strength should be in units of V/m.
Thanks!

Just look at the units. If you know how many volts are across the plates, just divide by the distance bwteen the plates and you have your answer.

Electric field inside the capacitor is a uniform one, depending only on potential difference across the plates U and separation between them d: E = U/d (which is obvious from the unit as well).

Energy stored in a capacitor is related to voltage as follows (assuming the dielectric constant is 1, in the absence of other information): W = (1/2) ε (A/d) V^2 And electric field strength can be calculated from voltage and distance: E = - V/d
