just a coupla quick questions:
1) in a parallel plate capacitor, we have field lines and equipotential lines. field lines show direction from the + to the - plate, but equipotential lines have no direction. why is this?
2) what happens to the electric field near the edges of the plates?
3) if you have a positively charged plate and place a negatively charged point charge above it, what does the electric field look like on them?
for part 1, i know that field lines have direction because it is an electric force acting in a certain direction, but I am not too sure about this equipotential stuff. i figure that the equipotential lines have no direction because they have no force acting on them at those points, I'm not too sure though...
for part 2, i know that between the plates the field is uniform and the strongest, so at the edge of the plates it becomes less intense and non-uniform?
for part 3, i know field lines go from + to - charges, but this is a plate and all the E lines radiate out from it, I am not sure if they all just go into the negative charge or what the deal is really
i dunno, any help would be appreciated
