The electron charge, often denoted as “e,” is the fundamental unit of electric charge carried by a single electron or proton. It has a value of approximately -1.602 x 10^-19 coulombs. The negative sign indicates that electrons have a negative charge, while protons have an equal positive charge.
The coulomb (C) is the unit of electric charge in the International System of Units (SI). It is defined as the amount of charge transferred when a current of 1 ampere flows for 1 second. In equation form:
1 coulomb = 1 ampere x 1 second
So, the charge of a single electron is approximately -1.602 x 10^-19 coulombs, and the charge of a single proton is +1.602 x 10^-19 coulombs.
