Electric Potential Questions!

  1. Feb 4, 2009 #1
    1. If V= 0 at a point in space, must E=0 there? If E=0 at some point must V=0 at that point? And examples for each?


    I'm pretty confused on both parts. I haven't really been understanding much of this electric charge/electric field stuff.

    I know, just from an equation at V= -Ed, but I don't quite understand this conceptually.

    When the electric field is not uniform, the electric potential at any point is given be
    E = - dV/dx i.e. negative tare of change of potential.
    If V is zero E must be zero. If E = 0, V may be zero or a constant.
