Clarification of electrical terms

  1. Jan 10, 2013 #1
    I am embarrassed to be asking such an elementary question, but I want someone to explain the difference between amps, watts, and joules. I tried a dictionary, but it wasn't specific enough.

    treplag, No one here on Physics Forums will spoon-feed you this information.

    If you are serious about learning electricity and electronics, this free downloadable book is the best choice for self study possible!

    “Here is the "Electricity - Basic Navy Training Courses" (NAVPERS 10622) in its entirety (or will be eventually). It should provide one of the Internet's best resources for people seeking a basic electricity course - complete with examples worked out (links to quizzes at end of chapters).
    Electricity - Basic Navy Training Courses
    NAVPERS 10622
    This book is intended as a basic reference for all enlisted men of the Navy whose duties require them to have a knowledge of the fundamentals of electricity.”

    As you go through this book if you have some doubts or specific questions, then do come right back here and post them. Members here are always willing to assist a true searcher willing to learn science.

    Bobbywhy - I appreciate the detailed information, and I will definitely check it out. But I don't appreciate the condescension. If I were not genuinely interested in an answer, I would not have wasted my time to post the question. I am new to this site, and receiving a supercilious response to my first post hardly encourages me to further my knowledge via this venue.

    treplag, I apologise if you felt condescension in my post. I certainly did not intend to insult your dignity. So, you used the dictionary to learn the difference between those three terms and were not satisfied. No surprise there.

    May I suggest you check Wikipedia. If you learn what each term means then their differences will be obvious. I used those terms in Google search and found these:

    Stop victimizing yourself, you asked a bad question and got called out on it.

    To make up for it, I'm expecting you to follow this up with a new post where you answer your own question—or, as Bobbywhy said, at least try and we'll see where that gets us. Good luck.
