Question

1)Name a device which converts mechanical energy to electrical energy
2)Explain the working principle of an electric generator
3)With the help of a diagram explain briefly the construction of an AC generator
4)Using Fleming's right hand rule explain how Alternating current is generated in an electric generator
5)What change will you make in the construction of an AC generator for obtaining Direct Current
6)Write 3 differences between AC and DC.

Answer 1

Answer:

1) A generator converts mechanical energy into electrical energy, while a motor does the opposite - it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field

2)Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. ... When the coil rotates, it cuts the magnetic field which lies between the two poles of the magnet.
