Energy is the capacity to do work. All living organisms require energy for carrying on their vital metabolic activities. The primary source of energy for living system is solar radiation. The radiant energy of sunlight cannot be utilised directly by all livi..

For a given power requirement, one has the choice of the relative values of I r m s and E r m s . That is, for the product to be a constant, we can choose a relatively large current I and a relatively small potential difference v or just the reverse. In an electric power distribution system, it is ..

Energy can neither be created nor destroyed. It can only be transformed from one form to anothe..

Law of Conservation of Energy - Let us see what is actually taking place in the following examples: Steam engine: The coal burns. Heat due to the combustion of coal converts water into steam. The expansive force exerted by the steam on the piston of the engine moves the locomoti..

Applying the law of conservation of energy, As the bob moves from mean position to the other extreme position E 2 , its kinetic energy decreases and potential energy increases. Energy becomes wholly potential at E 2 . As the bob moves from E 2 to th..
