Electricity And Its Type
Electricity And Its Type
Electricity is the branch of physics in which we study electric charges, at rest (electrostatics or static electricity) and in motion (current electricity). Electricity is one of the most important form of energy. It is produced because of charges. The matter is made up of electrons, protons and neutrons. Normally, a body has equal number of protons and electrons, and is therefore, electrically neutral. However, in certain situations, the balance of charges in a body is disturbed. For example, when a glass rod is rubbed with a silk cloth, some electrons get transferred from the glass rod to the silk. The silk cloth, which gains electrons, becomes negatively charged. And the glass rod, which is left with more protons than electrons, becomes positively charged.
Charged particles or objects can exert forces on each other. While like (similar) charges repel each other, unlike charges attract. Another important thing about charged particles is that they can flow, i.e., they can move in a particular direction. This flow of charged particles is called an electric current. There are two main types of electricity,
Electricity is the branch of physics in which we study electric charges, at rest (electrostatics or static electricity) and in motion (current electricity). An electric signal in a conductor travels at a speed of light i vaccum i.e.,
Static Electricity:
It is generated by rubbing two or more objects causing to build up of charges on an object. These charges do not flow continuously.The electricity produced is a property of charges at rest, and hence is called static electricity.
Current Electricity:
It is generated by the flow of electrical charge through a conductor across an electrical field. The electricity produced is because of an ordered motion of charged particles, and hence is called current electricity. Electric current is the continuous flow of electric charges (electrons) through a material. It means the flow of electric current in an electric circuit.
Direction of Electric Current:
Electric current flows in a particular direction. In an electric circuit, the electric current flows from the positive terminal to the negative terminal of the electric cell.

Students / Parents Reviews [20]
The experience was nice. I studied here for three years and saw a tremendous change in myself. I started liking subjects like English and SST which earlier I ran from. Extra knowledge gave me confidence to overcome competitive exams. One of the best institutes for secondary education.

10thWe started with lot of hope that Abhyas will help in better understnding of complex topics of highers classes. we are not disappointed with the progress our child has made after attending Abhyas. Though need to mention that we expected a lot more. On a scale of 1-10, we would give may be 7.

7thUsually we see institutes offering objective based learning which usually causes a lag behind in subjective examinations which is the pattern followed by schools. I think it is really a work of planning to make us students grab the advantages of modes of examination, Objective Subjective and Onli...
