comment Calculating Electric Field from a Potential Difference w/o Charge
Oh! I see what your saying now. Instead of postulating a charge distribution, using Gauss' law to find the potential, then solving for the distribution in terms of the known potential difference, you meant use Laplace's equation and the boundary conditions given to find the solution in cylindrical coordinates.

comment Calculating Electric Field from a Potential Difference w/o Charge
Do you mean the current shouldn't be proportional to the charge? I used your method, which worked quite well by the way, and I came out with the correct answer. However my current is not proportional to the charge. Wasn't the idea to eliminate the charge distribution from the electric field equation in the first place?

comment Calculating Electric Field from a Potential Difference w/o Charge
Ah I see what your saying. I'll try that and see what I come up with. I'm still curious about whether or not its actually possible to find the electric field with only the information I'm given or if, like you said, I have to postulate a charge distribution. If I'm not mistaken there physically has to be some sort of distribution, but I wonder whether or not it is necessary information.
