solar electric power systems

The solar system consists of the sun and all the objects that travel around it. The solar system includes the earth and eight other planets, along with the satellites (moons) that travel around most of them; planet like objects called asteroids; chunks ..

Many scientists believe that our solar system was formed from a giant, rotating cloud of gas and dust known as the solar nebula. According to this theory, the solar nebula began to collapse because of its own gravity. Some astronomers speculate that a nearby ..

It is present in abundance They have no moving parts and hence require little maintenance and work quite satisfactorily without any focusing device It does not cause any environmental pollution like the fossil fuels and nuclear power Solar cells last a longer time and have low r..

The heat and light energy emitted by the sun's radiation is called solar energy. Earth receives about 640 J of energy per second per square metre from the sun. The Sun's energy has two aspects. The 'heating effect' of sunlight, which is due to the infrared radiation present in the sun ra..

Power is the rate of doing work or in other words, it is the work done in one second. If a current of 'I' amperes flows through a conductor of resistance 'R' ohm for a time 't' seconds when the potential difference across its ends is 'V' volt, then the electric power ..

.A copper-constantan thermocouple is used between S 1 and S 2 .When sun's rays fall on S 1 , its temperature rises. The temperature of the junction (of the thermocouple) near S 1 increases. The galvanometer gives deflection. Now, current is passed through S 2 , so that temperature of S 2 becomes eq..
