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.
Which of the following are correct : (a) Static energy is generated by the flow of electrical charge through a conductor across an electrical field. (b) Current energy is generated by rubbing two or more objects causing to build up of charges on an object. (c) Charged particles or objects can exert forces on each other. While like (similar) charges repel each other, unlike charges attract. | |||

8thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
Shivam Rana
7thWhen I have not joined Abhyas Academy, my skills of solving maths problems were not clear. But, after joining it, my skills have been developed and my concepts of science and SST are very well. I also came to know about other subjects such as vedic maths and reasoning.

Yatharthi Sharma
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.
Manya
8thIt has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
Barkha Arora
10thUsually 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...

8thOne of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
Aman Kumar Shrivastava
10thMy experience with Abhyas Academy has been very good. When I was not in Abhyas whenever teacher ask questions I could not speak it confidently but when I came in Abhyas, my speaking skills developed and now I am the first one to give the answer of teachers question.
Upmanyu Sharma
7thAbhyas academy is great place to learn. I have learnt a lot here they have finished my fear of not answering.It has created a habit of self studying in me.The teachers here are very supportive and helpful. Earlier my maths and science was good but now it has been much better than before.
