PHYSICS IMPORTANT THEORY

Joules Law oh heating effect

 when a current 'i ' passes through a conductor of resistance 'r' for time 't' then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time


Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures remain constant.

What are the factors affecting the resistivity of method?
The factors like temperature, alloying, cold work, age hardening & mechanical stress affect the resistivity of electrical materials.

  Introduction All living organisms multiply or reproduce and produce offspring of a similar kind. Reproduction is an essential process for the existence of a species and the continuation of life. Here, in this chapter, we will learn about how different unicellular and multicellular organisms, such as bacteria, algae, plants, animals, and human beings, reproduce. Learn what the different reproductive structures are and about the modes of reproduction, such as cell division, vegetative reproduction, asexual reproduction, and sexual reproduction. Reproduction Reproduction is the process by which all organisms multiply in number and increase their population. Asexual Reproduction Asexual reproduction is a method of reproduction that involves only one organism. A single organism reproduces two or multiple organisms on its own. This is seen in all unicellular organisms, some multicellular organisms and a few plants. Sexual Reproduction The mode of reproduction involves two individuals; ...

The role of tribal uprisings in the freedom struggle

  The role of tribal uprisings in the freedom struggle of India cannot be undermined or overlooked. The tribes across the country played a significant role in challenging the British rule and fighting for the independence of their motherland. Their revolt against the colonial powers showcased a sense of unity and determination towards achieving freedom. The tribal uprisings were not only a response to the oppressive policies of the British, but they also represented a struggle for the preservation of their unique cultures, traditions, and way of life. The indigenous communities, with their deep-rooted connection to the land, felt a strong attachment to their territories, which were often subjected to exploitation by the British administration. Their resentment towards the encroachment on their lands and disrupting their traditional way of life fueled their desire to fight for independence. The Santhal rebellion of 1855-56, led by the Santhal tribe in eastern India, is one of the ...
