mechanical device transformed that 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..

There are two types of heat engines: external combustion engines and internal combustion engines. Steam engine is an example of external combustion engine. In such an engine, the fuel is burnt outside the working portion of the engine. A heat engine consists essentially of the following parts: i)..

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..

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..

Mechanism of Electrolysis - The process of electrolysis is exactly opposite to one that takes place in a voltaic cell. A voltaic cell or a battery uses its chemical energy to produce electrical energy. While in electrolysis, electrical energy..

In carrier mechanism, activated ions combine with carrier proteins and from ion carrier complex. This complex moves across the membrane and reaches the inner space by the expenditure of energy. Within the cytoplasm, the complex breaks to release the ions. The carrier moves out o..

Transformer - 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..
