Coulomb (C)

The coulomb (C) is the SI unit of electric charge, defined as the charge transferred by 1 ampere flowing for 1 second. One coulomb equals 6.242×10¹⁸ elementary charges (electrons or protons). Named after physicist Charles-Augustin de Coulomb. Formula: Q = I × t (charge = current × time).
