Other alternative source of energy for future is the nuclear energy derived from nuclear fission or nuclear fusion processes. The use of nuclear energy mainly requires its conversion into electrical energy. Out of the world's total energy..

Introduction - Do we use dry cells for operating electrical appliance? It is not impossible to tap continuous supply of energy from electrochemical cells. Electrical circuits in homes, factories and offices receive such energy form local power companies. In most countries the ..

Due to the ever increasing demand for energy, we need to develop specific devices that can harness energy from non-conventional sources like - solar energy, energy from the sea, geothermal energy and nuclear energy. We shall discuss each ..

Fossil fuels are the major source of energy on Earth. With the development of technology, the worlds consumption of the concentrated sources of energy like coal, petroleum and natural gas and uranium has increased. Very slow physical and chemical processes spread over many thou..

) are the major source of power in space stations and satellites. Solar energy has the following advantages: It is a renewable source of energy. It is easily available for the major part of the year, particularly in the tropical countries. It does not cause any pollution. The re..

. The loss in potential energy appears as a gain of kinetic energy and vice versa. The constant interchange of energy between potential and kinetic forms is essential for producing and maintaining any type of oscillation. In the case of the oscillating bob of a simple ..

Judicious use of Energy - In order to live and enable ourselves to do everyday work we need energy. The prosperity of a country depends upon the availability of energy. Huge amount of electrical energy is used to run the air conditioners, cold storage and oth..

>Negative sign indicates that induced EMF opposes any change in current. To maintain the current, the external source should do some work for whi..

In metals, the conduction band and valence band partly overlap each other and there is no forbidden energy gap. In insulators, the conduction band is empty and valence band is completely filled and forbidden gap is quite large = 6 eV. No electron from valence band can cross over to c..
