Calculate the work done by a Generator

[shinobi12]

Homework Statement

How much work is done by a generator or some other source of potential difference in moving 1 mole of electrons from an initial point of electric potential 9.00 V to where the potential is -5.00 V

Homework Equations

Im sure what to do

The Attempt at a Solution

I calculated the molecular weight of 1 mole of electrons, 5.49 x 10^-21 kg. Then I got extremely stumped. I'm a beginner at electromagnetism so I am not sure what to do at this point.

A mole of electrons is a Faraday. You might want to look up how many coulombs a Faraday is. This is a measure of charge.

As to Work that is generally just charge * change in voltage. (Vf - Vi) * coulombs
