Electrical Units Notation

Electrical units follow the notation of other scientific units.  The unit name is never capitalized, even if it is named after a person.  However, the abbreviation IS capitalized IF it is named after a person. 

I may refer to a coulomb in lower case.  However, when I am abbreviating the unit, I should use upper case, if I use the abbreviation for a coulomb (C).

I may write something like this:

The charge on the capacitor was 1.6 C.

OR

The charge on the capacitor was 1.6 coulombs.

Both are correct.

So is this:

The coulomb was named after Coulomb and its unit symbol is C.
