In a 280-turn automobile alternator, the magnetic flux in each turn is 2.50 x 10 cos out, where gis in webers, a is the angular speed of the alternator, and t is in seconds. The alternator is geared to rotate three times for each engine revolution. The engine is running at an angular speed of 1.00 x 10³ rev/min. (a) Determine the induced emf in the alternator as a function of time. (Assume & is in V.) 8- (b) Determine the maximum emf in the alternator.
