Q45: In a -turn automobile alternator, the magnetic flux in each turn is FB = cos vt, where FB is in webers, v is the angular speed of the alternator, and t is in seconds. The alternator is geared to rotate three times for each engine revolution. When the engine is running at an angular speed of rev/min, determine
(a) the induced emf in the alternator as a function of time and
(b) the maximum emf in the alternator.
