Solution

Verified by Toppr

The correct option is D All of the above
1. As we know that with the change of temperature the movement of electrons in a material changes and hence it affects the breakdown voltage of the material.
2. Thickness i.e. geometric is very simple concept. In an electrical material if the thickness of material is increases its breakdown voltage is also increased and hence the dielectric strength.
Hence option D is the correct answer.
3. The electric field has a direct relation with the breakdown voltage or dielectric strength. An increase in the electric field will result in increased dielectric strength.

Assertion :Dielectric material (dielectric for short) is an electrical insulator that can be polarized by an applied electric field. Reason: Electric field attracts the polarised or even non polarised atoms in a element and those atoms get collected on the surface

Q5

A parallel plate capacitor is to be designed with a voltage rating 1 kV, using a material of dielectric constant 3 and dielectric strength about 10⁷ Vm⁻¹. (Dielectric strength is the maximum electric field a material can tolerate without breakdown, i.e., without starting to conduct electricity through partial ionisation.) For safety, we should like the field never to exceed, say 10% of the dielectric strength. What minimum area of the plates is required to have a capacitance of 50 pF?
