A capacitor is an electronic device which stores energy in the form of the electrostatic field. It consists of two parallel conducting plates which are separated by an insulating material known as the dielectric. The commonly used dielectrics in capacitors are paper, mica, air etc. These conducting plates could be in the form of rectangular, circular, … Read more
When you read about circuits, you must come across terms analog and digital. Generally, electronic circuits can be analog circuits or digital circuits. Digital electronics involves quantities with discrete values, & analog electronics involves quantities with continuous values. Let see the definition of the terms analog and digital. Analog quantity The quantity that has continuous values … Read more
Transformer Noise When you crossed across a transformer in your locality, you might have listened to the humming noise coming from the transformer. It is quite annoying if the transformer is located in a residential area. The cause of transformer noise is the magnetostriction. We have written an article on Magnetostriction topic. As we know … Read more
Energy conservation means reduction in energy consumption but without making any sacrifice in the quality or quantity of production. It refers to increase the production from a given amount of energy input by reducing losses/wastage and maximizing the efficiency. Even though energy conservation reduce energy services, it can result in improved environmental quality, national security, personal financial … Read more
Biofuels are liquid fuels that have been derived from agricultural crops including conventional food plants and special energy crops. It may also be derived from forestry, agricultural or fishery products or municipal wastes, as well as from agro-industry, food industry and food service by-products and wastes. Biofuels provide a strategic advantage to promote sustainable development … Read more
Biomass energy refers to the direct burning of wood, waste paper, manure, agriculture or converting them into a fuel by certain micro-organisms when they digest them in the absence of air. They produce either alcohol or methane gas, which themselves give energy on combustion. Since biomass is obtained through the process of photosynthesis, therefore it … Read more
Hydro energy or hydraulic energy is the energy of moving water which is obtained when the gravitational descent of a river is compressed from a long run to a single location with a dam or a flume. It is not only a clean and non-polluting source of energy, but also one of the most important … Read more
Ocean energy is an indirect form of solar energy. The oceans and seas constitute about 70% of the earth’s surface area, so they act as a large reservoir of solar energy. On an average, the 60 million km2 of tropical seas absorb solar radiation equivalent to the heat content of 245 billion barrels of oil. … Read more
Wind energy is the kinetic energy generated by virtue of the movement of large air masses caused by differential heating of the atmosphere by the sun. It is one of the clean, renewable energy sources that hold out the promise of meeting a significant portion of energy demand in the direct, grid connected modes as … Read more
Solar energy is a primary source of energy which directly obtained from the sun by capturing the solar radiation and converting it into another form of energy to perform various useful activities. The solar energy received by the earth is approximately 1.4 kW/m2. It is known as Solar Constant or Solar Irradiance. For receiving the solar … Read more
