Question
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 (e.g. B, AC, CDF) if none of them are correct, enter the word none. A) With the capacitor connected to the battery, inserting a dielectric with kappa > 1 will increase Q. B) After being disconnected from the battery, increasing d decreases V. C) With the capacitor connected to the battery, inserting a dielectric with kappa > 1 will increase U. D) After being disconnected from the battery, decreasing d increases U. E) After being disconnected from the battery, decreasing d decreases C. F) With the capacitor connected to the battery, inserting a dielectric with kappa > 1 will increase C.Explanation / Answer
only A and D are correct
