Electric Permittivity

Definition

Electric permittivity is a measure of how easily an electric field can pass through a material. It quantifies the ability of a material to store electrical energy in an electric field.

Dielectric Constant: The dielectric constant is another term for electric permittivity. It represents the ratio between the capacitance of a capacitor filled with a particular material and the capacitance when there is vacuum or air between its plates.

Capacitance:

Capacitance refers to an object's ability to store electrical energy in an electric field. It depends on both the geometry and dielectric properties (electric permittivity) of the object.

Insulator: An insulator is a material that has high resistance to the flow of electricity. Materials with high electric permittivity often act as insulators because they impede the movement of charges within them.
