Question

What is a dielectric? How does it behave in an electrostatic field? How is introduction of a
dielectric slab between the plates of an air-filled parallel plate capacitor able to increase its
capacitance? Explain with suitable labelled diagrams.

Answer 1

Explanation:

I don't know I am sorry

Answer 2

• A dielectric (or dielectric material) is an electrical insulator that can be polarized by an applied electric field.

• Slight separation of charge (polarization) occurs in the dielectric. The positive charges shifts minutely towards the electric field and the negativ charges shifts minutely in the opposite direction of electric field. This reduces the electric field within the dielectric.

• The capacitance increases by a factor of dielectric constant.

• At the point when a dielectric material is presented between the plates of a charged capacitor, it becomes captivated (its inner + and - charges somewhat independent) by the electric field forced by the charges as of now on the capacitor plates. This polarization in the dialectric material sets up its very own electric field which restricts the current field, incompletely killing it, allowing increasingly (extra) charges to be put away on the plates for a similar voltage. Capacitance is in this way expanded. C = q/V
