Hydroelectric Power Plants
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..

The electricity produced from flowing water is called Hydroelectric power. The world's first hydroelectric power plant was set up in 1882 in Wisconsin USA. It had a very small output, supplying power only for about 250 light bulbs. But from this sma..

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 petro..
Construction and Working
Water flowing in high altitude rivers is stored in a man-made reservoir as shown in the figure. The kinetic energy of the flowing water is transformed into potential energy as the water level rises. This water is carried through pipes to the turbine situated at the bottom of the dam. The water ..

I really liked this tutoring. Helped me alot and gave me more ways to work a problem. awesome help and I even got the idea on these problems - kimi
Tutor is an excellent. I would say this tutor is an asset of Tutor Vista.. Excellent Job!!!!!!!
It's help ful session. I translate my book with him it was great time - William
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
