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.

After being disconnected from the battery, inserting a dielectric with ? will decrease C.

After being disconnected from the battery, inserting a dielectric with ? will increase V.

With the capacitor connected to the battery, inserting a dielectric with ? will increase U.

With the capacitor connected to the battery, increasing d decreases Q.

After being disconnected from the battery, increasing d increases U.

After being disconnected from the battery, decreasing d increases C

PLease and thank you
