A television set shoots out a beam of electrons. The beam current is 10E-6Amp
(10macroAmp. How many electrons srike the TV screen each second? How much charge strike the screen in a minute?
An ampere is a coulomb of electrons per second. If you divide that by the charge on one electron, you get amperes in electrons/second
coul/sec = e* electrons/sec
electron/sec= 1/e * amperes.
