Question
True or false
Which statements are true for two oppositely charged, isolated parallel plates: C=capacitance, U = stored energy (Q and -Q = charge on the plates). Note: Isolated plates can not lose their charge. Inserting a dielectric increases C. When the distance is doubled, U increases. When the distance is halved, Q stays the same. Inserting a dielectric increases Q. Increasing the distance increases the Electric field. When the distance is doubled, C increases. Inserting a dielectric decreases U.Explanation / Answer
the following statements are true:
When the distance is doubled, U increases.
Inserting a dielectric decreases U. (because C increases)
When the distance is halved, Q stays the same.
Inserting a dielectric increases C.(CK)
