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