Griffiths – Introduction to Electrodynamics problems

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.

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.

    Infact there is an instructor’s solution manual .But there is a mistake in it 2.1
    But u didnt workout it here

    • Alesha  On Wednesday, 13 November 2013 at 05:06

      i’d be interested to hear what you think the mistake is in 2.1.

  • ashok  On Monday, 8 April 2013 at 10:20

    interested in chapters 7 to 12

  • Jerry  On Sunday, 21 April 2013 at 03:15

    These solutions are very very helpful to me, you’ve explained it vary well.

  • Viktor.G  On Tuesday, 23 April 2013 at 16:44

    Good job fella , I am waiting (unpatiently) for the rest chapters . Heil Sagan.

  • Jerry  On Friday, 10 May 2013 at 07:51

    Five chapters yet?
    Please carry on with the good job, they’d been of great help to me.

  • Salma Ahmad  On Friday, 16 August 2013 at 15:57

    please upload the solution of problem 3.10 chapter special techniques.

  • Anonymous  On Wednesday, 25 September 2013 at 17:54

    Has anyone worked through the many parts of problem 2.54? I would really appreciate if someone could help out with them, in particular part g.

    These solutions have been incredibly helpful otherwise. Thanks!

    • growescience  On Thursday, 26 September 2013 at 08:22

      There are only 51 problems in chapter 2 (in the third edition). What edition are you using?

      • Anonymous  On Thursday, 26 September 2013 at 14:51

        Ahhh, my mistake. I was looking at the wrong edition. It turns out 2.54 in the 4th ed. is just about the same as 2.49 in the 3rd. Thanks for pointing out the mix-up!

  • Anonymous  On Sunday, 26 January 2014 at 02:05

    your method of explaining the concepts and the underlying reason of the maths is wonderful….GREAT JOB SIR!!!

  • Anonymous  On Thursday, 27 March 2014 at 22:28

    Thanks for maintaining this site! Much better than a solutions manual because you actually explain why you do what you do–so it’s possible to follow along and actually learn from the problems. I used your solutions for Griffiths’ Quantum Mechanics too!

  • koushik  On Wednesday, 23 April 2014 at 13:45

    I find the explanation to the solution really helpful. Million thanks for your effort in publishing this content.

  • Anonymous  On Saturday, 26 April 2014 at 23:19

    These are really very well done. Kudos and thanks!

    It is really helpful.. Thank u so much.thank u.

  • Christian  On Tuesday, 8 July 2014 at 17:15

    Hi, do you have the solution to the 8.9 Problem from the 4th Edition. I have my solution but I need to compare with someone.

    • growescience  On Tuesday, 8 July 2014 at 17:38

      Sorry, I don’t have the 4th edition.
