Key Terms

Permittivity
A measure of how easily a material can become polarized by an electric field.

Example: The permittivity of free space is a constant used in calculations.

Dielectric Strength
The maximum electric field a dielectric material can withstand without breaking down.

Example: Glass has a high dielectric strength, making it a good insulator.

Polarization
The alignment of dipoles in a material when exposed to an electric field.

Example: In water, molecules become polarized in an electric field.

Loss Tangent
A measure of energy loss in a dielectric material when subjected to an alternating electric field.

Example: A low loss tangent indicates efficient energy storage.

Capacitance
The ability of a system to store an electric charge.

Example: Capacitors store energy in electric fields.

Insulator
A material that resists the flow of electric current.

Example: Rubber is commonly used as an insulator.
