When the space between the plates of a capacitor having air is filled with a material of dielectric constant 6 its capacitance becomes?

capacitance is directly proportional to dielectric constant because c=q/v. v decreases(voltage or pot difference) n times when dielectric constant is n. therefore capacitance increases n times. for your question, capacitance becomes 6c, where c is initial capacitance.

What is meant by dielectric constant?

The dielectric constant is the ratio of the permittivity of a substance to the permittivity of free space. It is an expression of the extent to which a material concentrates electric flux, and is the electrical equivalent of relative magnetic permeability.

Does the dielectric constant affect the amount of charge stored on the plate?

The larger the dielectric constant, the more charge can be stored. Completely filling the space between capacitor plates with a dielectric increases the capacitance by a factor of the dielectric constant: C = κ Co, where Co is the capacitance with no dielectric between the plates.

When a dielectric medium is inserted between the plates of a capacitor then how is the capacitance changed explain?

When a dielectric medium is introduced between the plates of parallel plate capacitor, the dielectric gets polarized by the electric field between the plates. As a result, the electric field and hence potential difference between the plates of capacitor decreases.

What happens to the capacity of parallel plate capacitor when a dielectric medium is inserted between two charged plates?

When we place the dielectric between the two plates of a parallel plate capacitor, the electric field polarises it. The surface charge densities are σp and – σp. When we place the dielectric fully between the two plates of a capacitor, then it's dielectric constant increases from its vacuum value.

When a dielectric is inserted between the plates of the capacitor what happens to the dielectric?

Introducing a dielectric into a capacitor decreases the electric field, which decreases the voltage, which increases the capacitance. A capacitor with a dielectric stores the same charge as one without a dielectric, but at a lower voltage.

How does the energy stored in a capacitor change when a dielectric is inserted if the capacitor is isolated so Q does not change?

Yes, energy stored in the capacitor increases when a dielectric is inserted because the capacitance increases, and energy is proportional to capacitance. Force is required to insert the dielectric inside the capacitor so yes, this applied force does work to increase the stored energy.
