A parallel plate capacitor with plate separation d 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.
A) After being disconnected from the battery, inserting a dielectric with kappa > 1 will increase C.
B) After being disconnected from the battery, inserting a dielectric with kappa > 1 will increase U.
C) After being disconnected from the battery, decreasing d increases U.
D) With the capacitor connected to the battery, inserting a dielectric with kappa > 1 will increase Q.
E) With the capacitor connected to the battery, decreasing d decreases Q.
F) With the capacitor connected to the battery, increasing d increases C.
