Electric Field Review

These flashcards cover key concepts related to electric fields, charge properties, and related physical principles.

Charge

A property of a particle that causes it to experience a force in an electric field; can be positive or negative.

Quantization

The concept that charge exists in discrete amounts, represented by the equation q = ±Ne, where N is an integer and e is the elementary charge.

Conductor

A material that allows electric charge to flow freely due to the presence of free electrons.

Insulator

A material that does not allow electric charge to flow freely because all electrons are bound to atoms.

Semiconductor

A material whose electrical properties fall between those of insulators and conductors; can be modified by adding impurities.

Coulomb's Law

Describes the force between two point charges; stated as F = k_e (q_1 * q_2) / r^2, where k_e is the Coulomb constant.

Electric Field

A region around a charged object where other charged objects experience a force; represented by vectors pointing away from positive charges and toward negative charges.

Point Charge

An idealized model of a particle that has a charge but occupies no volume, often used in discussions of electric fields.

Electric Field Lines

Imaginary lines used to represent electric fields; they indicate the direction of the electric force on a positive test charge.

Induction

The process by which a charged object can cause a redistribution of charges in another object without direct contact.
