principle of ac generator

Electric Generator (AC) - The electric generator converts mechanical energy into electrical energy. The two types of generators are DC and AC generators: DC Generators - A cycle dynamo and a car dynamo are examples of DC gen..

When a straight conductor is moved rapidly in a magnetic field, then a current is induced in the conductor. It is based on the phenomenon of electromagnetic inductio..

The water flowing in a river is collected by constructing a high rise dam. This stored water is then allowed to fall from the top of the reservoir on to a water turbine located at the bottom of the dam. The fast moving water rotates the blades of the water turbine, which in turn rotates the armat..

When the blowing wind strikes across the blades of a windmill, it exerts a force on them due to which the blades of the windmill start rotating. This in turn rotates the shaft of the turbine and generates electricity. ..

Alternating Currents..

Solar Cells - Solar cells are expensive and are used only when supplying electricity becomes difficult. Solar cells are the devices where solar energy is directly converted into electricity. Solar cells are used in spacecrafts, radios, television, refrigerators, buoys and other navigation aid. Sola..
