Basic Electrical Test 12 Questions

  1. Jul 23, 2007 #1
    Hello there,

    I have these 12 simple electrical questions that I am having a lot trouble with.

    Would anyone please be able to perhaps have a look at them and give me there thoughts?

    The link is:

    You could either reply, or send me an email to damclay_64@hotmail.com

    Thanks in advance.

    Regards,

    Our thoughts?

    I think if there are specific things that are confusing you
    about the principles / mechanics of doing particular
    problems then you should describe what's
    specifically confusing you along with example cases of
    what manners of situations cause the confusion.

    Just sending a list of a bunch of really very technically
    unrelated questions from a bunch of areas of electronics
    doesn't help anyone resolve your sources of confusion
    about the principles.

    So I'm guesing you wont help?

    Help clarifying confusion about specific physical / electrical
    principles, yes, usually if I have time.

    Help by just giving a list of 50 answers to a series of random
    and various questions? No, that wouldn't help you learn
    anything more than working through all the similar
    practice problems your texts probably include along with
    the published answers to them.

    There's no substitute for taking the time to do a bit
    of studying and experimentation to try and understand
    something. Occasionally people can provide better
    explanations than those that may be given in certain
    texts / references, though.

    Your link does not work for me. I get a permission error.

    You are not going to get the kind of help you are asking for on this site. We require that you show some of your thoughts on the problem I would suggest that you do what you can on your "simple" questions, then post specific questions about the difficulties you encounter.

    It looks like a physic concept test. These are extremely important (given the modern understanding of physics teaching), and they don't work if students are exposed (familiarised) with the specific questions in advance. That, and the way you've censored parts of the scan makes you look guilty of something.

    as xez said in your other post, its not good for PF members to answer your question like the way you want. you ll have to be very specific. please try to come up with the problem that you are having solving the problem, not with the set of problems that you havent even tried yourself

    Besides the excellent recommendations of the other PF helpers, my thoughts on your electrical questions are the following:

    The first set, begs the question. How familiar are you with Ohm's Law? You probably will want to research this relationship and how it works.

    You also will want to look up resistors and capacitors (and while you're at it, inductors), how they combine in series and in parallel.

    Another concept you may want to look up is, "how do DC supplies combine when wired in parallel or in series?" (this one may be easily verified empirically, by wiring two small batteries in each configuration and measuring between their poles with a voltmeter).

    Finally, read up on AC and DC motors. Once you understand the areas I've mentioned, answering these questions will become trivial.
