- In a parallel-plate capacitor, the energy density u -that is, the potential energy per unit volume between the plates- should be uniform.
- We can find u by dividing the total potential energy by the volume Ad of the space between the plates.
- But since(C = ε0A/d), this result becomes
- However, (E=-ΔV/Δs), V/d equals the electric field magnitude E. Therefore;
