A parallel plate capacitor is attached to a voltage source providing 12 V. If an insulator of dielectric constant 6.0 is then inserted between the capacitor plates, what happens to the surface charge density on the plates, assuming the voltage source is still attached?

Question

Quizplus · Accepted Answer

The surface charge density increases by a factor of the dielectric constant (6.0) because the voltage source maintains the voltage, and the capacitance increases by the dielectric constant, leading to an increase in charge and thus surface charge density.
