Dielectric constant is the ratio of the permittivity of a substance to the permittivity of free space.
It is an expression of the extent to which a material concentrates electric flux.
As the dielectric constant increases, the electric flux density increases, if all other factors remain unchanged.
This enables objects of a given size, such as sets of metal plates separated by material of high dielecric constant,
to hold their electric charge for long periods of time,and/or to hold large quantities of charge.
Materials with high dielectric constants are useful in the manufacture of high-value capacitors.
