The charge of electron is -1.6*10^-19 coulombs. The charge of electron is the fundamental charge. Then why cant we take the charge of electron as the unit of charge? Why cant we choose the sign of charge differently i.e. the charge of electron is positive? Are there any advantages or disadvantages if the charge of electron taken positive? Why should the unit of charge be coulomb, which is the charge of a mol of electrons? What is the importance of mol?
