    Can anyone tell me if I should start studying on BASIC PRINCIPLES O

    Or the voltage, current, power, and energy a part of the Basi
    Principles of Electricity

    Need a reply ASAP...... I'm doing a self-study at home since I can'
    go to school yet due to financial problems..... :cry
  2. Begin with the principles!

    I once had an Electrical Theory class with an instructor that had a few
    misconceptions about basic principles. Nothing I could say would
    convince him that a coil of wire *sitting still* next to a magnet would
    NOT generate electricity.

    As others stated - start at the beginning. Having taught electronics at
    various levels in another life, I know that a lack of knowledge in the
    foundations can cause lots of problems later.

    Things to consider in your studies:

    1. Even though you have financial difficulties, if you can lay your
    hands on an old breadboard prototyping kit (such as the old HeathKit
    systems) and a cheap multimeter so you can actually experiment will
    help enormously.

    2. A decent knowledge of mathematics will help enormously. Electrical
    and electronic principles are physical processes, after all, and are
    described mathematically :)

    3. Try and get into the underlying physical principles - when you get
    confused (we all did), you can go back to first principles if

    4. Once well into it, a nodding acquaintance with calculus will help a
    great deal.

    Good Luck!

    I would start with the basics, if you really are a newbie. Yes, voltage,
    current, power and energy are basics, but there is, I'm sure, a more basic
    level, such as explaining how electricity works, when and where it flows,

    Do a little physics first; that helps.

    The best way to start learning this stuff is to do it in a methodical,
    organized way, not haphazardly finding material that you think will
    help you learn. The best way to do this on the cheap is to go to a
    local community college's book store and find a book on
    electricity/electronics basics. This will only cost you the price of
    the book. Some bookstores have used books available at a lower price.

    Find a book with DC or with DC & AC in the title. It will likely have
    the word Fundamentals in the title also. Look for a book of this

    Browse through the book. Review its table of contents. A good basic
    textbook will take you through the structure of the atom, the concepts
    of force, work, energy, and power. It will talk about temperature and
    heat, and basic electrical units. From there it will expand into
    discussions of current, voltage, and resistance. Finally, it will
    expand into general information/knowledge about basic circuits. If the
    book covers AC as well as DC, many of the concepts I've mentioned will
    be expanded upon as the book expands into AC. AC works in very similar
    ways to DC but you need to understand DC first.

    The strength of a GOOD basic textbook is that it presents all of the
    material you will need in an order that makes logical sense. You will
    learn what you need to know as it takes you from the most fundamental
    concepts of physics and electricity into a real understanding of how
    electricity and electric circuits work. This way you generally won't
    encounter a new concept until the preceding material prepares you for
    that concept--so you won't be unnecessarily discouraged by trying to
    learn something that it beyond your skills.

    I know it's summer so things at community college book stores might be
    slow, and the shelves at the book stores might be somewhat depleted.
    Research all the community colleges in your general area and visit all
    of them. Also, community colleges vary from place to place, so one
    might have a very strong electrical/electronics curriculum and another
    might not. Try your best to judge the book store and the books that
    you browse through.

    And this final word: Most of the words and concepts that you learn in
    this field of study will be new to you. Learning a new vocabulary, new
    concepts, and applying them all at the same time can be a tough
    challenge. Stay with it even if you get discouraged. If you get
    stumped while you're doing your self-study, come to this newsgroup and
    ask intelligent questions that show you're really trying to learn;
    people here will jump at the chance to help you. I think you will one
    day say to yourself, "Hey, I'm really beginning to understand this
    stuff!" It will happen. Hang in there!

    Gool luck.

    Textbooks get the equations right, but many of them contain all sorts
    of errors and misconceptions in their verbal descriptions. I go into
    these errors in depth on:

    billb electricity education articles

    You can use the above articles as a sort of "backwards learning
    experience;" learning about electricity by learning what electricity is
