An ideal air-filled parallel-plate capacitor has round plates and carries a fixed amount of equal but opposite charge on its pla
Vikentia [17]

Answer:

The new energy density is same as initial energy density u0 as it is independent of plate dimensions

Explanation:

As we know that energy density is total energy per unit volume

so we know that isolated plates of capacitor is placed here

C = \frac{\epsilon_0 A}{d}

here we have energy density given as

u = \frac{Q^2}{2(\epsilon_0 A/d)} Ad

so we have

u = \frac{Q^2d^2}{2\epsilon_0}

so it is independent of the dimensions of the plate while total charge on the plates is constant always

so energy density will not change and remains the same

I don’t know what to do
zavuch27 [327]

Answer:

So increasing the voltage increases the charge in direct proportion to the voltage. If the voltage exceeds the capacitors rated voltage, the capacitor may fail due to breakdown of the dielectric between the two plates that make up the capacitor.

Explanation:

A option.
