Question

Expression for instantaneous emf produced in ac generator

Answer 1

Answer:

it ya nhi ya ya i don't think I can get it done by e I don't know

Answer 2

The expression for instantaneous emf produced in ac generator is NABωsinθ

1. Principal of Ac generator is based don Faraday's Law
2. Faraday's Law when there is change of the magnetic flux in a electrical conductor there is an emf is induced .
3. Expression for instantaneous emf produced in ac generator is NABωsinθ
4. Here N is the number of turns in a coil ,A is  the area  ,B is the magnetic field ,ω is the angular speed of the coil and θ is the angle between surface of the coil and magnetic field .
