[Audio] Static electricity refers to charge that is not moving i.e., stationary charge.
An insulator can be charged electrically, by rubbing it while a conductor cannot.. 

Scene 2

[Audio] There are two types of charge: (a). Positive charge + (b). Negative charge -
The SI unit of charge is the Coulomb, denoted by C.
Negative charge is acquired if electrons are gained, and positive charge is acquired if electrons are lost.
All charges obey The Law of Electrostatic Charge, which states that, "like charges repel and unlike charges attract."
Electric charges can exist independent of each other..

There are two types of charge. (a). Positive charge +                                                           (b). Negative charge - The SI unit of charge is the Coulomb Negative charge is acquired if electrons are gained, and positive charge is gained if electrons are lost All charges obey The Law of Electric Charges which states that “like charges repel and unlike charges attract.” Electric charges can exist independent of each other

[Audio] Positively charged rod is brought near a neutral metal sphere, separating the charges.
The sphere is then connected to the ground. Negative charges flow from the ground to neutralize positive charges.
When the sphere is disconnected from the ground and the charged rod is removed simultaneously, the sphere is left with negative charge..

3. Sphere is disconnected
from ground.

4. Sphere has an
induced charge.

[Audio] Touching the sphere with a positively charged glass rod, allows for the passage of negative charges in to the rod, leaving the sphere positively charged.
Electrons flow from the piece of cloth into the polythene rod.
Electrons flow out of the acetate rod into the cloth which then becomes negatively charged.. 

Scene 5

When a polythene rod is rubbed with a cloth it becomes negatively charged. Electrons flow from the piece of cloth into the polythene rod. Electrons flow out of the acetate rod into the cloth which then becomes negatively charged

[Audio] This is a demonstration on charging of the spheres by separation of charges.. 

Scene 6

Charging through induction can be achieved in two ways: by earthing and separation of charges

[Audio] This is to demonstrate how to charge two spheres by separation of charges.. 

Scene 7

[Audio] Demonstration on charging earthing or grounding.. 

Scene 8

A charged strip is brought close to a neutrally charged metal sphere This causes a separation of charge within the sphere itself Earthing the sphere causes the negative charge to be repelled by the strip to the ground

Scene 9

Charge can be detected using a Gold Leaf Electroscope When a charged object is brought close to the metal cap, the gold leaf deflects upwards To find out the nature of the charge on the object, the electroscope must be charged first, i.e., only a charged electroscope can be used to detect the type of charge in an object

[Audio] Charged and discharged Gold leaf electroscope.. 

Scene 10

Discharging refers to the loss of excess charge It takes place through contact or ionization Dangers of ionization are minimized by earthing

[Audio] When excess charge has accumulated in the cloud it is discharged to the ground through ionization.
A lightning conductor discharges a cloud before it discharges on its own.
The lightning conductor should be made from a good conductor of electricity, and it should be taller than the structure it is protecting..

[Audio] The electric field is a region around a charged particle, where its electric force is felt.
Electric fields are illustrated with the help of electric field lines which begin at the positive charge and end at the negative charge
The diagrams demonstrate the field around single charges..
