- Glass
- \(BaTiO_3\)
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Dielectric constant shows the ability of a material to store electrical energy in an electric field.
Step 1: Rubber, alumina, and glass have moderate or low dielectric constants.
Step 2: Barium titanate \((BaTiO_3)\) is a ferroelectric ceramic.
Step 3: Ferroelectric ceramics have very high dielectric constants.
Step 4: Therefore, among the given options, the highest dielectric constant is shown by: \[ \boxed{BaTiO_3} \]
