Which is the most superior dielectric out of the following ?

Solution (By Examveda Team)

A dielectric is an insulating material that can withstand electric stress without breakdown.

The superiority of a dielectric is judged mainly by its dielectric strength and insulating capability.

Among the given options, glass has a very high dielectric strength and excellent insulating properties compared to air, paper, and bakelite.

Air has the lowest dielectric strength, while paper and bakelite are moderate dielectrics but inferior to glass.

Therefore, glass is the most superior dielectric among the given options, making Option B the correct answer.
