| THE FUNDAMENTAL CONCEPTS - CHARGE | ||
The charge of one electron could be used as a unit of electrical charge, since charges are created by displacement of electrons; but the charge of one electron is so small that it’s impractical to use. The practical unit adopted for measuring charges is the COULOMB, named after the scientist Charles Coulomb. One coulomb is equal to the charge of 6,280,000,000,000,000,000 (six quintillion two hundred and eighty quadrillion) or (6.28 x 1018) electrons. |
