Capacitance of a parallel plate capacitor C=ε0AdC=ε0Ad A parallel plate capacitor is charged (battery is disconnected) then the plates are pulled apart, the capacitance decreases while the charge remains the same ∵Potentialdifference=ChargeCapacitance∵Potentialdifference=ChargeCapacitance ∴∴potential difference increases

Assuming that the capacitor is connected across a constant voltage source keeping V constant, increasing the distance between the parallel plates will decrease C. at a constant V, an increase in C will decrease the charge Q that the conductors can hold.
