Coulomb's Law and Gauss's Law Lecture

These flashcards cover key concepts related to Coulomb's Law and Gauss's Law from the lecture notes.

Coulomb's Law

Describes the force between two charged objects; states that the electric force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Electric Field (E)

A physical field around a charged particle that exerts a force on other charged particles.

Gauss's Law

States that the total electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity of free space.

Gaussian Surface

An imagined closed surface used in Gauss's Law, typically chosen for its symmetry to simplify calculations.

Charge Density (ρ)

The amount of electric charge per unit volume, surface, or length.

Electric Field Intensity

The strength of the electric field at a point in space, often denoted as E and measured in volts per meter (V/m).

Integral Form of Gauss's Law

Expresses Gauss's Law using surface integrals to relate electric field and charge.

Divergence Theorem

A mathematical statement relating the flux of a vector field through a closed surface to the volume integral of the divergence of the field.

V/m

Volts per meter, the unit for measuring electric field strength.

Volume Charge Density (ρv)

The charge per unit volume of a material, measured in coulombs per cubic meter (C/m³).
