Electric charge is a fundamental physical property that determines electromagnetic interactions.
Electrically charged objects interact by exerting forces, of attraction or repulsion, on each other. The unit of measurement of the electrical charge quantity in the International System of Units is the coulomb, represented by C, which was named after the French physicist Charles Augustin de Coulomb.
