A parallel plate capacitor with adjustable plate separation d and adjustable area A is connected to a battery. The capacitor is fully charged to Q Coulombs and a voltage of V Volts. (C is the capacitance and U is the stored energy.) Give all correct answers concerning a parallel-plate capacitor charged by a battery (e.g. B, AC, CDF ).

A) With the capacitor connected to the battery, increasing d increases U.

B) With the capacitor connected to the battery, increasing the area A will decrease U.

C) After being disconnected from the battery, increasing the area A will increase C.

D) With the capacitor connected to the battery, increasing the area A will increase Q.

E) After being disconnected from the battery, increasing d increases V.

F) With the capacitor connected to the battery, increasing d increases C.
