Question

By removing the dielectric between the plates of an isolated charged capacitor, the energy density is?

Answer 1

Answer:

Energy Stored would Decrease

Explanation:

When the dielectric is removed, the charge on the plates, Q, does not change. The capacitance C decreases, so the energy must increase. ... If the plates of the capacitor are connected to an ideal battery, then the voltage, not the charge, would remain constant, and the energy stored would decrease.
