A parallel plate capacitor by 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 with a battery. For each statement below, select True or False.
1. True False. After being disconnected from the battery, decreasing d decreases C.
2. True False. After being disconnected from the battery, decreasing d increases U.
3. True False. After being disconnected from the battery, inserting a dielectric with? Will decrease U.
4. True False. After being disconnected from the battery, inserting a dielectric with? Will increase V.
5. True False. With the capacitor connected to the battery, inserting a dielectric with? Will decrease C.
6. True False. After being disconnected from the battery, increasing d increases V.
