The diagram shows two parallel metal plates connected to a d.c. power supply through a resistor. There is a uniform electric field in the region between the plates. Which change would cause a decrease in the strength of the electric field?

1. Aa small increase in the distance between the plates
2. Ba small increase in the potential difference between the plates
3. Ca small increase in the resistance of the resistor
4. Da small increase to the area of both plates
