solar power or wind power

As energy is the capacity to do work, power can also be defined as energy consumed in unit tim..

Power - Imagine two students positioned at track A and track B of 100m length shifting 10 bricks from one end of the track to the other end. What is the amount of work done by each one of them? The amount of work done is same but the time taken to perform the work varies. In order to find..

A contractor wishes to lift a load of bricks from the sidewalk to the top of a building by means of a winch. Since we know the expression for work, we can calculate work to be done by the force applied by the winch to lift the load. We are interested in the rate at which it is done, that is, ..

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..

. Eventually, solar eruptions occurred, producing a solar wind. In the inner solar system, the wind was so powerful, that it swept away most of the lighter elements - hydrogen and helium. In the outer regions of the solar system,..

Solar cells convert light energy of the sun into electrical energy. They provide almost the complete power for required space crafts and artificial satellit..

Electric Power - 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 ..
