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 ..

Electricity is obtained from flowing water. Water from the dam is allowed to flow through the tunnels at a high pressure. Turbines convert the potential energy of the water into electrical energy. About 23,800 MW of energy is generated by hydel power in India. Hydel power requir..

P = E r m s I r m s cos q . The product E r m s I r m s is called apparent power, whereas the P is called the true power. The term cos f is called the power factor. The current through pure L or pure C, which consumes no power for its maintenance in the circu..
