a potential diff of 12v is causing electrons to flow through a wire so that 2x10^20 electrons pass a point in the wire in 1min.
calculate the charge which passes the point in one min given that the charge is 1.6x10^-19C

anonymous · Answer

Well if the charge of one electron has a charge of 1.6x10E-19, which it does, and if 2x10E20 of them pass in a minute, you could multiply those numbers togetehr to get the total charge that goes by.

So 2x10E20x1.6x10E-19=3.2 x10=32
