power capacity of an electric power plan

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

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..

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 generat..

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 hei..

Tidal Power - The tides are formed due to the gravitational force of attraction between the earth, sun and moon. During high tides sea water is trapped in a reservoir, and released later to drive turbines, which in turn produces electricity. The block diagram given below illustr..

Power - 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 don..

The energy of flowing water is utilised to produce electricity on a large scale at hydroelectric power plant..

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..
