    First off, hello to all. I am learning electrical fund. I have a question in a test that i cant find an answer to. If someone would help i wud appreciate it..

    "if the two wires connecting a battery to a circuit were reversed, the direction of current flow through the circuit would:

    A.reverse
    B.remain the saim
    C.create an alternating current
    D.depend on the amount of voltage

    Thanks

    If you use a multi meter to measure with it, it will show a negative sign. So what does that mean?:)

    Current flows from negative(or ground) to positive. (How we were taught) Think about that, and use current direction arrows on a circuit drawing.

    TP, I don't know why these guys are so indirect with regard to your question. The answer is: Changing the terminals of a battery around would most definitely cause current to flow the other way.

    Tpizana, Too bad you feel that way, giving you the answer is the easy way out, and will not help you when the classes get tough.(and they will) There are techs out there who can't calculate simple voltages and currents. They give a bad name to those who give their best in class and industry.
