low power methodology

In amplitude modulation, the sidebands contain the signal. The power in the sidebands is the only useful power. The power carrier by the side bands is only 33.3% even when there is 100% modulation. If modulation is 50%, then power carried by the sidebands is..

The demand for electricity varies at different times of a year. One big disadvantage is that the wind, waves and tides do not occur at all time and hence cannot guarantee steady production of electricity. Hydroelectric power stations can solve this problem. When the demand is l..

Thermo-couples can be used to generate electric power using Seebeck effect, in remote areas. This can be done by heating one junction of a thermo-couple in a flame (e.g., of kerosene lamp) and keeping the other junction in air at room temperature. The thermo-emf so generated can be used t..

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. Fo..

In 1986 at Chernobyl, Russia an experiment at the nuclear power station went wrong. An explosion blew open the reactor and released radiation into the atmosphere. Over 6 tonnes of nuclear material escaped causing release of radiation. Radiation, if absorbed by an organism can cause damage..

Advantages of Using Solar Energy - It is present everywhere. It is available in plenty. It does not cause any environmental pollution like the fossil fuels and nuclear power. Solar cells last a longer time and have low running costs. In the first half of the twentieth century solar e..

Argon is used mainly to provide an inert atmosphere in high temperature metallurgical processes (arc welding of metals or alloys) and for filling electric bulbs. It is also used in the laboratory for handling substances that are air-sensitive. Helium is a non-flammable and light gas. Hence, it is u..

Metallic Conduction Electrolytic Conduction Passage of Charge by electrons Passage of charge by ions in molten and aqueous state. Passage of charge brings about only physical changes. Does not involve transfer of matter Brings about physical and chemical changes. Involv..
