Question
Consider two oppositely charged, isolated parallel plates separated by distance D, with capacitance C, charge Q, and stored energy U. D is small compared to the dimensions of the plates. For each statement below, select "True" or "False"
1)Inserting a dielectric increases Q.
2)Inserting a dielectric decreases U.
3)When D is halved, Q stays the same.
4)Increasing D, decreases the E field.
5)When D is doubled, C is doubled.
6)Because of charge conservation, inserting a dielectric leaves C unchanged.
7)When D is doubled, U decreases.
