Gauss's law

Gives the electric flux through a closed surface as the enclosed charge divided by the vacuum permittivity. It is used to find electric fields in situations with high symmetry.

\Phi_E = \frac{Q}{\varepsilon_0}

What the symbols mean

electric flux through a closed surface (V·m)
net electric charge enclosed by the surface (C)
permittivity of free space (F/m)
