In a 240-turn automobile alternator, the magnetic flux in each turn is OR = 2.50 x 10** cos ot, where OR is in webers, o is the angular speed of the alternator, and t is in seconds. The alternator is geared to rotate five times for each engine revolution. The engine is running at an angular speed of 1.00 x 10 rev/min. (a) Determine the induced emf in the alternator as a function of time. (Assume E is in V.) (b) Determine the maximum emf in the alternator. v
