In what unit is electric charge measured?

Electric charge is measured in Coulombs, represented by the symbol C. The Coulomb is the standard unit of electric charge in the International System of Units (SI). It quantifies the amount of electricity flowing through a circuit and is defined based on the flow of electric current. Specifically, one Coulomb is equivalent to the charge transported by a constant current of one ampere flowing for one second.

Understanding that electric charge is distinct from other physical quantities is essential. For example, Newtons measure force, Joules measure energy, and Watts measure power. Each of these units serves a different purpose in physics, further highlighting the specificity of the Coulomb as a measure of electric charge. This knowledge is fundamental in studying electricity and electromagnetism, making it clear why the correct answer is Coulombs, C.
