Unit of Charge The charge on an electron is so small that it is not convenient to select it as the unit of charge. In practice, coulomb is used as the unit of charge i.e. SI unit of charge is coulomb abbreviated as C. One coulomb of charge is equal to the charge on 625 X 1016 electrons, i.e. 1 coulomb = Charge on 625 x 1016 electrons Thus when we say that a body has a positive charge of one coulomb (i.e. +1 C), it means that the body has a deficit of 625 x 1016 electrons from normal due share. The charge on one electron is given by | |
