Introduction
Electric field by any surface can be calculated using the concept of electric flux.
Pre-Requisites:
Basic introduction about electric flux.
Activity:
Find out how the field varies in the case of infinite long wire and infinite plane sheet.

Practical examples around us
| Examples | Explainations |
|---|---|
| Every system of charges | Field in the every system of charges can be calculated using Gauss's law. |
What you learn in Theory:
Total flux through any surface is zero if the charge enclosed by the surface is zero.
What you learn in Practice:
Gauss's law is used where we find any symmetry in the charge distribution, this enables us to take use of Gaussian surface.
