Electric Field Intensity

  1. Feb 16, 2006 #1
    Does the intensity of the electric field between two charged parallel plates stay constant regardless of the distance between the plates, assuming of course that the plate area is such that the plates do not become point charges?

    There are edge effects, but if the area or lateral dimensions are much larger than the separation, the electric field intensity for parallel (flat) plates is constant, but still proportional to the separation.



    If one lateral dimension were to shrink, then the plate would become a line charge, and if both lateral dimensions were reducted, the plate would become a point charge.
