electric powers

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..

The energy of flowing water is utilised to produce electricity on a large scale at hydroelectric power plants. This is another conventional source of energy derived from flowing water. Dams are constructed across the waterfalls to derive electrical energy from i..

Rose's mother prepares food in an oven, which consumes 200 KWh of electricity per day and the power company charges $10 per 100 KWh. Which of the tables shows the correct relationship between the electricity consumed and the amount charged? => Table 1 or Table 2..

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..

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..
