Question:
Which of the following material has high dielectric constant?
Which of the following material has high dielectric constant?
Show Hint
Barium titanate \((BaTiO_3)\) is a ferroelectric ceramic and has a very high dielectric constant.
Updated On: May 7, 2026
- \(NaCl\)
- Mica
- Diamond
- \(BaTiO_3\)
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Dielectric constant measures the ability of a material to store electrical energy in an electric field.
Materials with high dielectric constant are useful in capacitors and electronic ceramics.
Barium titanate:
\[
BaTiO_3
\]
is a ferroelectric ceramic material.
Ferroelectric materials have very high dielectric constants due to strong polarization effects.
Because of this property, barium titanate is widely used in capacitors, dielectric ceramics, and electronic components.
Mica is a good dielectric, but its dielectric constant is much lower than barium titanate.
Diamond and sodium chloride do not have dielectric constants as high as barium titanate.
Therefore, the material having high dielectric constant is:
\[
BaTiO_3.
\]
