Question

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

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.

Answer 2

Answer:

With the battery connections removed, the charge on the capacitor is stranded on the capacitor plates so remains constant. Adding the dielectric increases the capacitance.So, the energy is decreased.
