All Flashcards
What is the effect of placing a material with high electric permittivity between charged plates?
The electric field between the plates decreases.
What happens when like charges are brought near each other?
They repel each other.
What happens when opposite charges are brought near each other?
They attract each other.
What happens when an electric field is applied to a dielectric material?
The material becomes polarized, with electrons rearranging to create charge separation.
What is the effect of increasing the distance between two charged objects?
The electric force between them decreases.
What is electric force?
The fundamental force governing interactions between charged objects, causing attraction or repulsion.
Define electric permittivity ().
A measure of how easily a material polarizes in an electric field.
What is free space permittivity ()?
The permittivity of a vacuum; a fundamental constant in physics formulas.
Define polarization in the context of electric fields.
The rearrangement of electrons in a material under an electric field, creating charge separation.
What is the difference between conductors and insulators in terms of permittivity?
Conductors have high permittivity due to free electrons, while insulators have low permittivity due to restricted electron movement.
