A potential difference of 480V is established between largeparallel, metal plates. Let the potential of one plate be 480V andthe other be 0V. The plates are separated by d = 1.70cm.
a) Sketch the equipotential surfaces that correspond to 0, 120,240, 360, and 480 V.
b) In your sketch, show the electric field lines. Does yoursketch confirm that the field lines and surfaces are mutually perpendicular?
