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".
T/F Inserting a dielectric increases Q.
T/F When D is doubled, C is doubled.
T/F Inserting a dielectric decreases C.
T/F Because of energy conservation, inserting a dielectric leaves U unchanged.
T/F Increasing D, increases the E field.
T/F When D is doubled, U decreases.
T/F When D is halved, Q stays the same.
