Magnitude of the charge on 1 electron = 1.602x10-19 Coulombs
so the question is basically asking how many electrons make up one coulomb
How do you calculate the number of electrons that must flow in 1 second to give a current of 1 amp?
is the charge in Coulombs, is current in amps and is time in seconds.
is the integer (whole number i.e. 1, 3, 79 etc. not decimals) number of electrons (or protons) and is the electron charge
Equating the two equations as they're both equal to charge, where
Substitute in the values and find
