coulomb
-----------------------------------------
Coulomb (symbol C) is a derived unit for electrical charge in SI; the base units are:
1 C = A x s
So, the coulomb is the electrical charge transported by an ampere in one second.

The ampere is the SI Base Unit or electric current. It is NOT derived from the charge (coulomb) but from the force resulting from its magnetic effect. The ampere is defined in terms of the force between two, parallel, current-carrying conductors due to the interaction of their magnetic fields. The coulomb, on the other hand, is an SI Derived Unit, based on the ampere and the second.
The SI unit of electric current is the ampere. While it is an SI base unit, it can also be considered to be a combined unit, coulombs per second.
The SI derived unit of electric charge is the coulomb(C).In electrical engineering, it is also common to use the ampere-hour (Ah).In chemistry and particle physics, it is common to use the elementary particle charge (e) as a unit.Independent of units, the symbol Q often denotes charge.
Capacitors are measured in Farads or microfarads.
an electrical charge is measured in Coulombs, which is equal one ampere-second. That is, one ampere of current through a plane is equivalent to one coulomb of charge passing through the plane per second.Current
