    Meaning there are 6,250,000,000,000,000,000 free electrons in wire?

    What really is free electron? An electron that is not attach in any atom?

    What is an atom? I understand it is the smallest unit of matter, so what is it?

    What is the difference between
    horsepower and torque?

    What really is voltage. i understand it is a potentional force or push and it pushes the current. So why is it push? Is it because of the attraction analogous to gravity?


    why every thing has resistance (exc. superconductivity )


    thnx

    A free electron is one that is given away for nothing; you are not "charged" for it. Heh heh.

    You can't put 5 questions in one post and expect good answers, especially when some of the answers would need a whole book to explain them.
