The coulomb is named after Charles-Augustin de Coulomb. As with every SI unit named for a person, its symbol starts … See more

The SI defines the coulomb by taking the value of the elementary charge e to be 1.602176634×10 C, but was previously defined in terms of the force between two wires. The coulomb was originally defined, using the la… See more
