Question

8. The maximum electric field that a dielectric medium of a capacitor can withstand without break down (if its insulating property) is called its:
A) Polarisation
B) Capacitance
C) Dielectric strength
D) None of these

Answer 1

Answer:

sorry i dint known this answer

Answer 2

Answer:

The maximum electric field that a dielectric medium of a capacitor can withstand without break down (if its insulating property) is called its dielectric strength i.e.option(C).

Explanation:

Let's analyze the options one by one and we will get our answer.

Option A: Polarisation

When an electric field is applied to a capacitor the dielectric material induces charges on the capacitor such that the negative charges in the material orient themselves towards the positive electrode and the positive charges shift towards the negative electrode. This is called polarisation.

Option B: Capacitance

It is the capacity of the capacitor to store charge.

Option C: Dielectric strength

The maximum strength of an electric field that a dielectric medium can withstand without breakdown (of its insulating property) is called its dielectric strength.

Hence, among the given options the correct answer is option (c) i.e.Dielectric Strength.
