Introduction
We can also find the number of field lines passing through any area, termed as Flux.
Pre-Requisites:
Knowledge about and basic electric field and electric field lines.
Activity:
Observe what will happen if the angle between electric field and area vector changes regularly.
Real Life Question:
How can we determine the electric field without coulomb’s law, If we are given a particular area?

Practical examples around us
| Examples | Explainations |
|---|---|
| Every system of charges present | In every system of charges present in the universe, there exists a field by charges. |
What you learn in Theory:
Electric field produced by any charge can be shown by some lines, called field lines. Number of field lines represent the electric flux passing through any surface area.
What you learn in Practice:
Electric flux is the number of field lines passing through any surface area, which gives the strength of electric field.
