Dot product: ##\vec{D} \cdot\vec{E}## in Si-units

- Relevant Equations
- D dot E

I'm trying to calculate the electrostatic energy, and I'm wondering what happens when I dot the D-field and E-field, with Si-units V/m**2. This is my equation:

D dot E = (-4x(epsilon) V/m**2)(-4x V/m**2) + (-12y(epsilon) V/m**2)(-12y V/m**2)

Are the final Si-unit still V/m**2 or V**2/m**4?

D dot E = (-4x(epsilon) V/m**2)(-4x V/m**2) + (-12y(epsilon) V/m**2)(-12y V/m**2)

Are the final Si-unit still V/m**2 or V**2/m**4?
