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
