Introduction
We know that electric field is a vector, thus we represent it by field lines in vector form.
Pre-Requisites:
Knowledge about and basic electric field.
Activity:
Observe how electric field lines show the strength of electric field at any point.
Real Life Question:
How we can determine the direction of electric field if we are given the field lines.
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Electric field lines | Imaginary representation of the electric field around a charge. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Text book | You can learn more about the electric field lines from your text book. |
Real life uses :
Microphones, Electric guitar, Hydro power plants etc.
Places to visit :
Your school physics lab, you can also refer to your text book for more knowledge.
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, which can be shown by some vector lines. |
What you learn in Theory:
Electric field produced by any charge can be shown by some lines, called field lines. Where the crowd of field lines is, more the value of electric field. These also show the direction of the electric field.
What you learn in Practice:
Field lines are imaginary things that show the existence of electric field. More number of lines means denser electric field.
