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.
Most electrical units are named after people:

volt | V | Allesandro Volta |
ampere | A | André-Marie Ampère |
ohm | Ω | Georg Ohm |

watt | W | James Watt |
joule | J | James Prescott Joule |
seimens | S | Ernst Werner von Seimens |
hertz | Hz | Heinrich Hertz |
tesla | T | Nikola Tesla |
weber | Wb | Wilhelm Eduard Weber |
henry | H | Joseph Henry |
maxwell | Mx | James Clerk Maxwell |
gauss | G or Gs | Carl Friedrich Gauss |
