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