Two similar flat conducting plates are arranged parallel to one another, separated by a distance ##s##. Let the area of each plate be ##A## and suppose that there is a charge ##Q## on one plate and ##-Q## on the other. ##\phi_1## and ##\phi_2## are the potential values at each of the plates. When the field is treated uniform its magnitude must be ##(\phi_1 - \phi_2)/s##.
I guess it is a trivial fact that field must be ##(\phi_1 - \phi_2)/s## but I don't get how ? is there a derivation for it ?[/QUOTE]
