Sub Topic Code : 101_12_02_09_06 |
Topic Name : Electrostatics Of Conductors |
|
Sub Topic Name : Electric Field At The Surface Of The Charged Conductor |
|
Introduction
The electric field is normal to the surface,
which is true for both signs of
?. For ? > 0, electric field is normal to
the surface outward; for
? < 0, electric field is normal to the surface inward.
Pre-Requisites:
Conductors
Activity:
Different conductors in our home like wires.
Real Life Question:
What is the electric field at the
surface of a charged conductor?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Conductors | A conductor is an object or type of material which permits the flow of electric charges in one or more directions. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Pill box | It can be used to check the total flux through the pill box |
Real life uses :
Conducting wires are used in our wiring system of our house.
Places to visit :
Physics lab for better understanding.
Practical examples around us
| Examples | Explainations |
|---|---|
| Pill box | The total flux through the pill box comes only from the outside (circular) cross-section of the pill box |
What you learn in Theory:
