PHY 102 Capacitors and Capacitance Objective Question
Take CBT

Question

What is the dielectric constant (K) of a material?
Options
A The ratio of the permittivity of the material to the permittivity of free space (K = ε/ε₀)
B The ratio of capacitance with dielectric to capacitance without dielectric
C A dimensionless number greater than or equal to 1
D All of the above
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

The dielectric constant K = ε/ε₀ = C/C₀, and is always ≥ 1. It measures how much the dielectric increases capacitance.

Hint

Also called relative permittivity.
