a lesson on charge, work, and energy

So, I'm thinking it's time for another physics lesson...and this time we're going with a bit of electricity. Electricity and magnetism have never been my favorite--just ask Dr. Hemmati, my professor for that subject in undergrad!    ~Don't get me wrong; I'm definitely a big fan of all the wonderful things we have because of electricity.

This semester, though, I'm taking Classical Electrodynamics I, my first grad school electricity course. The professor is great and has this novel idea that he should teach us things (sadly a rare thing among way too many teachers...but ...
