A little problem on dimensional analysis

[jeremy22511]

Homework Statement

The dimensions for all sorts of energy must be equal.
Then the following should hold:
By E=Fs and E=VIt,
[Fs] = [VIt]
[M][L]²[T]^-2=[V][Q]

Now, according to some online lectures I watched some time ago, the dimensions of time, length, and mass are the three fundamental dimensions and all other dimensions can be derived with the three. So I was wondering if I could simplify the dimension of the p.d. and the coulomb into the three dimensions.

Would appreciate any help. Thanks.

Homework Equations

The Attempt at a Solution

I asked my high school teacher the other day and he said that the dimensions for the coulomb and p.d. are already the simplest...

In an electric field F = E*Q
And V = E*d
Therefore Energy = V*Q = E*d*F/E = F*d.

Oh. I didn't realize it was that simple. Thanks.
