David Griffiths: Introduction to Electrodynamics

Here are my solutions to various problems in David J. Griffiths's excellent textbook Introduction to Electrodynamics, Third Edition. Obviously I can't offer any guarantee that all the solutions are actually correct, but I've given them my best shot.

After some consideration, I've decided to repost this index to the solutions. I understand that some folks may be concerned that I am providing 'free' answers to problems that some students have been assigned as homework, but there are several points that should be made:

These solutions are the only ones that I've worked out so far, so please don't ask me to post "the rest of the chapters" as I haven't worked on those yet. I will get to them eventually.

There is an official site listing errata in the textbook. If you're confused by something in the text itself, it's worth having a look here to see if there is a typo on that page.
