define one coulomb of charge?
Coulomb is the SI unit of electric charge which is equal to the amount of charge transported by a current of one ampere in one second.
It is denoted by C.
It is named after Charles- Augustin de Coulomb who discovered the Coulomb’s law.
Mathematically,
1 Coulomb = 1 Ampere × 1 second.
So, C = As
