What is 1 coulomb of charge? What is the unit of charge?

1 coulomb charge is defined as 6.24*10¹⁸ electrons that is

1C= 6.24*10¹⁸

The unit of charge is coulomb. 

One coulomb is equal to the amount of charge from a current of one ampere flowing for one second. One coulomb is equal to the charge on 6.241 x 10¹⁸ protons. The charge on 1 proton is 1.6 x 10^-19 C. Conversely, the charge of an electron is -1.6 x 10^-19 C.One coulomb equals 6,240,000,000,000,000,000 electrons.

The coulomb is a unit of charge, which can be expressed as a positive or negative number, which is equal to approximately 6.2415×10¹⁸ elementary charges. Accordingly, an elementary charge is equal to approximately 1.602×10^-19 coulombs.

Matters can be charged with three ways, charging by friction, charging by contact and charging by induction. When you rub one material to another, they are charged by friction.

The unit for measuring electric charge is the coulomb (C), named after Charles-Augustin Coulomb, an 18th-century French physicist. Coulomb developed the law that says "like charges repel; unlike charges attract." A coulomb is defined as the amount of charge transported by a current of one ampere for one second.These two types of electrical charges - positive and negative - are said to be opposite types of charge. And consistent with our fundamental principle of charge interaction, a positively charged object will attract a negatively charged object.
