Acurrent of 1.40 a flows in a wire. how many electrons are flowing past any point in the wire per second?

The current is the quantity of charge Q flowing through a certain point of the wire in a time interval of :


So, by using this relationship and I=1.40 A, we can find the charge passing any point in the wire in 1 second:


To find how many electrons corresponds to this charge, we should divide this value by the charge of a single electron ():
electrons
