What is the current in a wire if 3.4•10 to the 19 electrons pass by a point in this wire every 60 seconds

1.6 x 10^19 electrons per coulomb 

current (amperes) is defined as the number of coulombs per sec flow 

amps = #of electrons /( electrons per coulomb) / 60 sec 
= 3.4 x 10^19 electrons /1.6 x 10^19 electrons per coulomb /60 sec 
= .035 amps
