Introduction
In practical life, charge cannot be assumed as discreet, it has to be treated as continuous.
Pre-Requisites:
Introduction about discontinuous system of charges and quantization of charges.
Activity:
Find out the electric field of the objects of continuous charges like- charged wire, plane sheet, a spherical surface etc.
Real Life Question:
Why we use the continuous charge distribution over the discreet system in practical life?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Linear charge density | It is the charge flowing per unit length of the charged wire. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Text book | Text book will give you more idea about the continuous charge distribution. |
Real life uses :
To calculate the field in real life surfaces.
Places to visit :
You can refer your text in order to get more knowledge about it.
Practical examples around us
| Examples | Explainations |
|---|---|
| every system of charges | every system of charges around us is made up of small elements, which are to be considered as continuous charges. |
What you learn in Theory:
Field due to continuous charges can be found same as the discreet charges but we have to sum up the effects of individual surface elements.
What you learn in Practice:
In practical life, charges are considered as continuously bound rather than in quantity. Also it ignores the principle of quantization of charge.
