Physics

A parallel plate capacitor with adjustible plate separation dand adjustible area A is connected to a battery. The capacitor isfully charged to Q Coulombs and a voltage of V Volts. (C is thecapacitance and U is the stored energy.) Give all correct answersconcerning a parallel-plate capacitor charged by a battery (e.g. B,AC, CDF).

A) After being disconnected from the battery, increasing the area Awill increase C.
B) With the capacitor connected to the battery, increasing the areaA will decrease U.
C) With the capacitor connected to the battery, increasing dincreases U.
D) With the capacitor connected to the battery, increasing the areaA will increase Q.
E) After being disconnected from the battery, increasing dincreases V.
F) With the capacitor connected to the battery, increasing dincreases C.
