what is powers

Power - Imagine two students positioned at track A and track B of 100 m 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 or..

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

Absolute alcohol is miscible with petrol but industrial alcohol is not. However, in the presence of benzene, industrial alcohol can be mixed with petrol. This alcohol used for generating power is called power alcohol..

Electricity is produced by converting the potential energy of water (from a height) into the kinetic energy of flowing water. Hydroelectricity or hydroelectric power is produced, when large quantities of water stored in dams at a suitable height, are released to fall from a height. A dyn..

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 consumed P..

Electricity is obtained from flowing water. The flow of water is checked by building a dam. The water from the dam is allowed to flow through the tunnels at a high pressure. Turbines convert the potential energy of the water into electricity. About 23,800 MW of energy is generated by hydel pow..

Resolving Power - The ability of the instrument to resolve the images of two point objects lying close to each other. Due to the wave nature of light each point object produces its own diffraction pattern, which overlap, and the image can no longer be identified. Resolving power..
