For a dielectric which of the following properties hold good?

For a dielectric, the following properties generally hold good:

1. Polarization: When a dielectric is placed in an external electric field, it becomes polarized. This means that the centers of positive and negative charges within the material shift slightly, creating an internal electric field that opposes the external one.

2. Dielectric Constant: Also known as the relative permittivity, this is a measure of how much the electric field in the dielectric is reduced compared to a vacuum. A higher dielectric constant indicates a material that more effectively reduces the field.

3. Dielectric Strength: This is the maximum electric field that a dielectric can withstand without undergoing electrical breakdown (where it becomes conductive). Dielectric strength is usually given in Volts per unit thickness (like kV/mm).

4. Energy Storage: A dielectric material can store electrical energy by means of the polarization of its molecules. This property is utilized in capacitors, where dielectric materials are used to increase the energy storage capacity.

5. Non-conductivity: Ideally, a dielectric material does not conduct electric current, as it is an insulator. However, at very high electric fields (beyond the dielectric strength), dielectric breakdown can occur, and the material may become conductive.

6. Frequency Dependence: The dielectric properties of a material can depend on the frequency of the applied electric field. For example, the dielectric constant can decrease with increasing frequency
