Sub Topic Code : 101_12_01_08_02 |
Topic Name : Electric Field |
|
Sub Topic Name : Electric Field Due To A System Of Charges |
|
Introduction
We know that field can exist due to one charge only, but if there are multiple charges present in the system, then what is the electrical field?
Pre-Requisites:
Knowledge about coulomb’s law and basic electric field.
Activity:
Find out on which quantities electrical field due to charge depend.
Real Life Question:
Usually electric field doesn’t occur from a single charge. What happens when more than one charge are there in the system?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Principal of superposition | A law used to add the vector quantities. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Book | You can learn more about this 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 affect force. |
What you learn in Theory:
There exists a field even when only one charge is present in the system, but when more than one charges are there field gets added up due to individual charges.
What you learn in Practice:
The field existing due to the multiple charges is the addition of field due to every charge, present in the system.
