1 Coulomb is the charge that moves when 1 Amp flows for 1 Second, so here we have 3 x 12 = 36 Coulombs 1 Coulomb is equal to 6.24151 × 10^18 electrons (thanks Wikipedia).So the number of electrons that flows when 3A flows for 12 S is : 3 x 12 x 6.24151 × 10^18 electrons = 2.24694 x 10^20 electrons....

charges flow= 3*12=36 Coulombs.# of electrons=36 C/(1.6*10^-19)=22.5*10^19 electrons.... Show More
