A parallel plate capacitor is attached to a voltage source providing 12 V.When an insulator of dielectric constant 6.0 is then used to fill the air space between the capacitor plates,what happens to the surface charge density on the plates if the voltage source is still attached?

Question

Quizplus · Accepted Answer

The surface charge density increases by a factor equal to the dielectric constant when the voltage source remains attached, as the capacitance increases by the dielectric constant while the voltage remains constant.
