If you are searching for full analysis of electrostatics, then welcome on our website. In this article, I will provide you with complete relevant information about electrostatics with proper explanation. I will describe you step by step topics of Electrostatics.

Electrostatic Important Topics

Electric Charge

Electric charge is the property associated with the matter due to which it produces/experiences electric and magnetic effects. It is a scalar and is addictive in nature.

Generally, electric charge is an intrinsic property of the elementary particles like liked protons, electrons, etc., of which all the objects are made up of.

Charges that something which is possessed by the material objects and which enables them to exert the force and also responds to the force.


Conservation of Charge

According to the principle of conservation of charge, we can neither created nor destroyed electric charge. The cost can completely be transmitted from one body to another.

The magnitude of Charge: If a body gains or loses electrons, then the magnitude of the charge developed on the body is Q=ne.

where e= fundamental charge, n= integer

The quantisation of Charge: It means did the total charge developed in the body is always equal to the integer multiple of the fundamentals charge.

Law of Conservation of Charge: In an isolated system, the total charge remains the same.

The two charge bodies interact with one another: It means that the two charged bodies exert force on another. This force is known as electrostatic force. This electrostatic force will be attractive if the two charged bodies carry charges of opposite nature while the electrostatic force will be repulsive if the charges are of the same kind.

Frictional Electricity

The property of rubbed substances due to which they attract light objects is called electricity. When the rubbing of friction develops, the electricity is called static or frictional electricity.

Both electric and magnetic phenomena can be derived from charged particles. Magnetism arises from charges in motion. A body is said to be electrified or charged when it shows the property of attraction.

What is Electrostatics?

It is the study of electric charges at rest. In this article, we study the forces, fields and potentials associated with static charges.

Applications of Electrostatics:

The attraction and repulsion between charged bodies have many industrial applications.  Some of them are mentioned below:

  • In electrostatic loudspeaker
  • While spraying of paints and powder coating.
  • Use in the flyash collection in Chimneys.
  • It can be useful in the xerox copying machine.
  • In the design of a cathode ray tube used in radar and television.

So these are some essential applications of electrostatics. Some scientist use of terms vitreous and resinous for the two kinds of charges.

The vitreous charge is developed on glass rod when rubbed with silk while the resinous charge is produced on ember when rubbed with wool. For example, a ground glass rod generates resinous electricity while a highly polished ebonite rod develops vitreous electricity.

Obviously, any two charged objects belonging to the same column will repel each other while the use of different columns will attract each other.

Some important points of Electrostatics:

Different substances can be arranged in a series in such a way that if any two of them are rubbed together, then the one occurring earlier in the series acquires a positive charge while the other occurring later acquires a negative charge.

The cause of charging is the actual transfer of electrons from one material to another during rubbing.

You should know that protons are not transferred during rubbing.

The material with a lower work function loses an electron and becomes positively charged.

Conductors are the ones from which electric charges can flow smoothly.

As an electron has a finite mass, therefore, there always occurs some change in mass during charging.
