Electric Field lines running high to low voltage

  1. Sep 11, 2011 #1
    1. The problem statement, all variables and given/known data
    Show from the given equation Vb -Va=-intergral a to b (E x ds) that the electric field lines run from higher voltages to lower voltages. Also show from this equation that the electric field lines are perpendicular to equipotential lines.

    The voltage in our experiment ran from 0-6 across the conductive paper (provided by a dc power supply.


    2. Relevant equations
    Vb -Va=-intergral a to b (E x ds)

    3. The attempt at a solution
    I don't really know where to get started

    6-0=-integral(E x ds)

    Please point me in the right direction.

    Care to copy the lab directions and show them here?
