Calculate the work done by a Generator

Click For Summary
SUMMARY

The discussion focuses on calculating the work done by a generator in moving 1 mole of electrons from an electric potential of 9.00 V to -5.00 V. The key formula for this calculation is Work = Charge × Change in Voltage, where the charge for 1 mole of electrons is equivalent to 1 Faraday (approximately 96485 coulombs). The change in voltage is determined by subtracting the initial potential from the final potential, resulting in a total voltage change of -14.00 V.

PREREQUISITES
  • Understanding of electric potential and voltage
  • Knowledge of the concept of a mole and Faraday's constant

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
 
thanks i really appreciate your help
