hi,
We see theoretical discussion of Electric field inside the charged capacitor is confined in the space between the plates and E.d = potential difference between plates. Considering the battery terminal(let us say positive terminal), wire and left plate or top plate, being in the same potential, let us try calculating the potential on the outside surface of top plate. Since the electric field is zero, the work done in carrying a positive test charge from infinity to the outside surface of the top plate, will be zero. But the potential cannot be zero since battery terminal, wire and the plate are at the same potential. What is wrong here?
