Aarav Mckenzie · Answer 1

Let the potential difference remains same. So, by insertion the dielectric, the capacitance

C' = KCo

As V remain same, so Q' = KQo

Energy, U' = 1/2 C'V² = KCo

Electric field, E' = E / K

Where, k be the dielectric constant.

Thus, V remains same

Energy increases

C increases

E decreases

Q increases.
