Question

What can increase the peak emf in an ac generator without changing the frequency?

Answer 1

Step-by-step explanation:

The peak emf in an AC generator is given by :

`\epsilon=NAB\omega`

Here,

N is number of turns in the generator

A is area of the coils

B is magnetic field

`\omega` is angular frequency

It is clear that the peak emf in an ac generator depends on :

• The number of turns in the generator
• Area of coils
• Magnetic field
