Usually one makes the approximation that the electric field between charged parallell metal plates is homogenous, and that its strength is given by E=U/d, where U is the voltage between the plates and d is the distance between them.

However, I would like to know what the field strength really is, in my case between two charged circular plates. That is, how does the field strength between two charged parallell circular plates depend on the voltage, the distance between the plates and the position?

Thanks in advance!
