Gauss's Law

Electric flux through a closed surface.

Formula

ΦE=Qencε0\Phi_E = \frac{Q_{enc}}{\varepsilon_0}

Variables

Q_{enc}Enclosed charge
\varepsilon_0Permittivity

Example

The electric flux out of any closed surface depends only on the charge inside it.

Did You Know?

Gauss's law is one of Maxwell's four equations that together describe all of electromagnetism.
