Physics

A parallel plate capacitor with plate separation d isconnected to a battery. The capacitor is fully charged toQ Coulombs and a voltage of V volts. LetC be the capacitance and U the stored energy.Select True or False for eachstatement.
1. After being disconnected from the battery, decreasingd increases C.
2. With the capacitor connected to the battery, decreasingd increases C.
3. With the capacitor connected to the battery, decreasingd decreases Q.
4. With the capacitor connected to the battery, inserting adielectric with Îº > 1 will decrease Q.
5. With the capacitor connected to the battery, decreasingd increases U.
6. With the capacitor connected to the battery, inserting adielectric with Îº > 1 will decrease U.
