Homework Help: Electrostatic Field Lab Question

  1. Feb 27, 2012 #1
    1. The problem statement, all variables and given/known data
    Based on Volts and distance, calculate the max Electric Field between lines.

    2. Relevant equations

    3. The attempt at a solution
    We basically connected a 6Vdc battery to a plate containing two conductors and use a multimeter to plot the lines of flux of the field. To find the max magnitude of the electric field I would apply coulombs law two a point between the two conductors with charges 6 and -6 Volts. However, I don't know how to do that using volts and distance, since I an not given the charges in coulombs. If the electric field can also be defined as Volts/Meter, how would one go about doing that?

    Generally we have that ##\mathbf{E}=-\nabla V##, which can also be written as ##\int \mathbf{E} \cdot d{s} = -\Delta V## along some path.

    For a small step in the direction of the electric field this means: ##E = -{\Delta V \over \Delta s}##.
