In solar cooker, solar radiation spreads at all the points, whereas in solar concentrator it is concentrated at a particular point.
Black coated sheets, glass plates, vessel, etc.
A glass sheet transmits solar radiation into it as a semiconductor.
In thermal power plants, heat is converted into steam energy which runs the turbine to get electrical energy.
Characteristics are generally classified in to renewable sources of energy and non-renewable sources of energy, which is used in heating, producing po...
Solar collector is a form of collector which collects solar energy and transforms the solar energy to the form which can be utilized according to the ...
When any substance tends to burn for a particular temperature it is called the ignition temperature for that particular substance.
Heat energy is measured in units of joules or calories (1 calorie = 4.18 joules). The heat generated by fuels when they burn in joules or calories mea...
Solar energy and wind energy.
Solar radiations are converted into electricity in solar cell which is used in traffic signal lights, etc.
