Question

Which of the following is true in case of a dielectric strength, when the thickness of the material increases?

• A. Remains same
• B. Decreases
• C. Increases
• D. Becomes zero

Answer 1

The correct option is B Decreases

The dielectric strength is a ratio of voltage applied across the plates to thickness of the dielectric material.

i.e. $K=\frac{V}{t}$

Hence, as the thickness of the material increases, the dielectric strength decreases.

So, option (c) is the correct answer.
