electrical power losses

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..

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, will t..

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

Domestic Electric Circuit - Electric power is usually generated at places which are far from the places where it is consumed. Distribution of Electricity from Grid The power is transmitted over long distances at high voltage to minimize the los..

Domestic Electric Circuits - Electric power is usually generated at places which are far away from the places where it is consumed. At the generating station, the electric power is generated at 11,000 volts. This voltage alternates at a frequency of..

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..
