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.

With the capacitor connected to the battery, increasing d decreases Q.
After being disconnected from the battery, inserting a dielectric with will increase V.
After being disconnected from the battery, inserting a dielectric with will increase C.
With the capacitor connected to the battery, inserting a dielectric with will decrease U.
With the capacitor connected to the battery, increasing d increases U.
After being disconnected from the battery, decreasing d increases C.
