उत्तर
A parallel plate air capacity 'C' farad, potential 'V' volt and energy 'E' joule. When the gap between the plates is completely filled with dielectric both V and E decrease.
Explanation:
Note: We have taken into account keeping the battery and capacitor separate. Potential difference results from the introduction of dielectric inside the parallel plate capacitor.
V = `"V"_0/"K"`
Also, energy decreases, i.e., U = `"U"_0/"K"`
