power source switching

Renewable sources of energy are produced continuously in nature and are non-depletable. Sources like water, sunlight, air, tidal energy, nuclear energy, geothermal power, are not exhaustible. A non-renewable source of energy gets depleted over a certain peri..

". It is measured in ohms. A conductor with a high resistance 'resists' the current, and only a small current flows. A low resistance allows a higher current for a particular voltag..

Tidal Power - The tides are formed due to the gravitational force of attraction between the earth, sun and moon. During high tides sea water is trapped in a reservoir, and released later to drive turbines, which in turn produces electricity. The block diagram given below illustrates the t..

Energy - 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 deposit, such as..

Characteristics of Sources of Energy - A good source of energy should have the following characteristics: It should do a large amount of work per unit mass or volume - it means that the output energy must be more than the input energy. It should have high calorific value. It sho..

Advantages - 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..

In an electrical circuit, energy is supplied by the source of EMF, stored by the capacitive and inductive elements and dissipated in resistive element..

Average Power Associated with LCR Circuit in Series - In an electrical circuit, energy is supplied by the source of EMF, stored by the capacitive and inductive elements and dissipated in resistive elements. Conservation of energy requires that, at any particular time, the rate a..

Hydro-electric Power Plant (Hydro-electric Energy) - The energy of flowing water is utilised to produce electricity on a large scale at hydroelectric power plants. This is another conventional source of energy derived from flowing water. Dams are constructed across the..
