losses in a transformer

(i) Copper loss is the energy lost due to heating of copper coils of transformers. (ii) Iron loss due formation of induced current in the iron line resulting in lot of heat. (iii) Leakage of magnetic flux. All flux linked with primary may not be linked with secondary...

Apparent Loss of Mass - You must have seen that when substances like wood, wax, coal, oil, etc. are burnt, they seem to disappear, or leave a very small quantity of residue. It looks as if the mass is much lesser. Well, the loss of some mass of these substances is only apparent...

E s < E p i.e., K <1 n s < N p If we assume there is no loss of power, Out put power = Input power E s I s = E p I p..

Characteristics of a Food Chain - In a food chain, a) there is repeated eating in which each group eats the smaller one and is eaten by the larger one. Thus, it involves a nutritive interaction between the biotic components of an ecosystem. b) the plants and animals which depend successively on one..

Domestic Electric Circuit - Electric power is usually generated at places which are far from the places where it is consumed. Distribution of Electricity from Grid The power is transmitted over long distances at high voltage to minimize the loss of energy during transmission. For a given ..

For a step up transformer k>1 and for a step down transformer,..

Environment refers to the natural elements that make up the earth and surround living organisms The abiotic or physical aspects of the environment refer to elements like air, soil, water etc. The biological or biotic components of environment are the plants and animals Natural resources con..

Thus, the total energy is a constant. At the equilibrium position, y = 0 At the extreme position, y = A, As the body oscillates, there is a transformation between kinetic energy and potential energy, maintaining the total energy const..

According to this theory, the reactant molecules must come together to form an arrangement of atoms/molecules that facilitates the formation of products. This arrangement of the reacting species is called the transition state. A simple way of visualizing the concept of the transition state is to th..
