A basic question on Ohm’s law and the definition of voltage
Amps is coulombs/second. 1 coulomb  6.242×10e18 electrons, if you want to find out how many electrons, find how many seconds and multiply it by how many amps are flowing through the resistor. This gives you coulombs, to find the number of elections, multiply it by 6.242×10e18 .   

Joules is watts·second. If you know how many secconds and how many watts, you can determine how much charge has gone through the resistor.

It should be easy to tell how many watts is going through the resistor given the above diagram.
