Calculate the number of electrons constituting one coulomb of charge

Answer»

We know that the CHARGE of 1 electron = 1.6 x 10POWER minus19 coulomb
thus, 1.6 x 10power minus 19C of charge=1 electron.
therefore 1C= 1/1.6 x 10 power minus 19 electrons
                    = 10 power19/1.6 electrons
                    = 10 x 10power 18/1.6 electrons
                    =6.25 x 10 power18 electrons
