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. (C is the capacitance and U is the stored energy.) Answer the following questions regarding the capacitor charged by a battery. For each statement below, select True or False.

1.After being disconnected from the battery, inserting a dielectric with ? will increase V.
2.After being disconnected from the battery, increasing d decreases V.
3.With the capacitor connected to the battery, inserting a dielectric with ? will increase U.
4.After being disconnected from the battery, increasing d increases U.
5.After being disconnected from the battery, inserting a dielectric with ? will increase C.
6.After being disconnected from the battery, decreasing d decreases C.
