transformation of mechanical energy into electrical energy

fig. 1.2 - Energy transfer and energy transformation Examples of energy transformation 1. Photosynthesis - in which green plants transform radiant solar energy into chemical energy that gets stored as potential ene..

Energy can be defined as the ability to do work. A good source of energy would be the one which would: do a large amount of work per unit volume or mass be easily accessible be easy to store and transport and be economical Fossil Fuel Fossil fuel is a hydrocarbon de..

We can see many situations in which energy is transferred to or from objects and systems, similar to money being transferred between accounts. In each situation, we assume that the energy that was involved can be accounted for, that is, energy cannot appear or disappea..

Electric charges and current attract or repel each other, i.e., they exert forces on each other. Thus, work needs to be done in order to move them with respect to one other. The energy associated with this work is called electrical or electromagnetic energy...

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 syst..

Energy Flow - Energy is the capacity to do work. Solar energy is transformed into chemical energy by the process of photosynthesis, and is stored in plant tissue and then transformed into mechanical and heat forms during metaboli..

Flowing or moving air is called wind. By the virtue of this motion, the wind possesses kinetic energy. A windmill is used to make practical use of wind energy. The force of the wind rotates the blades of the windmill. Wind should flow continuously with certain minimum speed (sa..

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..

Illustration of Conservation of Mechanical Energy - Conversion of gravitational potential energy to kinetic energy: When a body falls from a certain height, its kinetic energy increase..
