Electric charge

  1. Nov 18, 2007 #1
    hi there,
    i've read books and some web sites and i'm wondering this electric charge? Is it something physical (compose of matter)? some say its the one causing the electric field,
    by analogy, is it like mass has something to do with gravity?
    thank you

    Yea you can draw the same analogy as mass causing gravity. Here, a charge emanates an electric field.

    You're lucky. I just finished a web page which contains a definition of electric charge. See

    Go to the second section which is entitled "Charge."

    Electric charge is a fundamental conserved property of some subatomic particles, which determines their electromagnetic interaction. Electrically charged matter is influenced by, and produces, electromagnetic fields. The interaction between a moving charge and an electromagnetic field is the source of the electromagnetic force, which is one of the four fundamental forces. I hope it was a good help . Richard 14
