### Potential Difference

On page 45 of the course reader, it talks about potential difference between electrodes. Can someone explain in depth what that means?

### Re: Potential Difference

Potential difference, also known as voltage, is the difference in electric potential between the two electrodes and is equal to the work done per unit of charge against an electric field to move a charge between the electrodes. Negatively charged particles are pulled towards higher potential differences, and positively charged particles are pulled towards lower voltages. The conventional current thus always passes from high potential difference to low potential difference.
