Question

When voltage is increased to a certain value the current between the two plates is reduced to zero. Why does increasing the voltage stop the current?

Answer 1

Realy not zero but, very low?

Answer 2

Eventually there is no more "room" for any additional charge so the flow reduces actually it reduces exponentially depending on the capacitance ,i.e. the capacity of the two plates and the resistance in series with them. Initially there is no excess charge on the plates and the initial current is maximum and then decreases as the plate accumulate charge until the total charge reaches a quantity equal to the capacitance times the voltage. the capacitance depends on the area of the plate and the separation. Capacitance is equal to the area divided by the separation.
