Homework Help: Electric Field help!

  1. Jan 20, 2008 #1
    1. The problem statement, all variables and given/known data
    We had an experiment in class where we had a glass pan with a piece of copper and lead with positive and negative leads attached. I have to figure out in which direction the electric field goes. We measured the voltage an numerous places in the pan. The numbers go bigger as they went form the lead to the copper. Can someone assist me in determining the direction of the electric field?

    If you have a positive charged body and place a positive test charge near the body, the electric field will be in the direction of the force on the test charge. i.e. E=F/q where E and F are vectors.
