Problem
The peak emf of an ac generator depends on certain design and operating parameters.
Answer the following, giving reasons:
(i) How will the peak emf change if the angular speed of the coil is doubled while all other factors remain the same?
(ii) How will the peak emf change if the magnetic field strength is halved, keeping every other factor unchanged?
