Detailed explanation-1: -A coulomb (C) is the standard unit of electric charge in the International System of Units (SI). It is the amount of electricity that a 1-ampere (A) current carries in one second (s). A quantity of 1 C is equal to the electrical charge of approximately 6.24 x 1018 electrons or protons.
Detailed explanation-2: -The SI unit of electric charge is the coulomb which is a derived SI unit and is represented by the symbol C. A coulomb is defined as the amount of charge that passes through an electrical conductor carrying one ampere per second.
Detailed explanation-3: -Coulomb’s law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects. The S.I. unit of electric charge is “Coulomb".
Detailed explanation-4: -1 coulomb equals to 3 x 109 esu.
