Yogita Ingle 6 years, 3 months ago

Dielectric Constant of a substance can be defined as:

The ratio of the permittivity of the substance to the permittivity of the free space

It expresses the extent to which a material can hold electric flux in it.

Dielectric Constant Formula

It is mathematically expressed as:

κ = ε/ε₀

Where,

κ is the dielectric constant
? is the permittivity of the substance
?0 is the permittivity of the free space
