Problem with Neumann boundary condition AD/DC module

I want to calculate the electrical resistance of sphere with two small contact surfaces, first one is the inlet with V=1 Volt the second is the outlet with V=0 all the surfaces i impose n.j=0.
The solution shows that the electrical current is not a same in the inlet and outlet, i calculate it by integring the electrical density on the two surfaces. I obtain that the n.j on all the surfaces of the sphere exept the inlet and the outlet is not equal to zero.
How to impose a correct neumann boundary condition in this case?
How to calculate the electrical resistance i obtain a very weak resistance of order of 10^-5
Thak you
