Gauss's law relates the electric flux through a closed surface to the net electric charge enclosed by the surface. It states that the total electric flux through any closed surface is equal to 1/ε0 times the net charge enclosed, divided by the permittivity of free space ε0. Gauss's law provides an easier way to calculate electric fields than Coulomb's law and can be used to find electric fields when you know the charge distribution inside the surface.

1. Gauss’s Law
Introduction

2. Gauss’s law relates electric field to the
charge distribution producing that field.
Gauss’s law gives us much easier way to
calculate electric field then Coulomb’s
law
Gauss’s law deals with the electric field
and concept of electric field lines is
central concept for studying Gauss’s
Law

3. Bases of Gauss’s Law
Flux through any closed
surface is measure of
total amount of charge
inside it
Any charge outside the
surface would not
contribute to the total
flux
