Coulomb: The Unit of Electric Charge

The mechanical force of repulsion and attraction among the charges is the basic method by which electricity develops itself as evident. Any charge is an instance of static electricity because of the protons and electrons are not in motion.

The charge of several billions of protons or electrons is essential for common applications of electricity. Thus, this is convenient to define a practical unit known coulomb(C) as equivalent to charge of 6.25 x 10 18 protons or electrons stored in a dielectric. The analysis of static charges & their forces is known as electrostatics. Q or q is the symbol of electric charges which standing for quantity. This unit is named after Charles A. Coulomb, a French physicist, who calculated force among the charges.
