Answer 1

Answer:

a) electromagnetic induction

Answer 2

Principle behind Electric generator is electromagnetic induction.

Explanation:

• Electromagnetic induction is based on Faraday's law.

• Output frequency of wind turbine is 50 Hz. So, it means the in one second the turbine rotates 50 times. The revolution of turbine is 50 times per second.

• Muppandal is advantages area because this area is too windy most of the time (in most seasons).

• City A is better option because wind speed is more in city A which is 120 m/s.
