Φ In a 290-turn automobile alternator, the magnetic flux in each turn is B = 2.50 × 10-4 cos wt, where is in webers, w is the angular speed of the alternator, and t is in seconds. The alternator is в B geared to rotate three times for each engine revolution. The engine is running at an angular speed of 1.00 × 10³ rev/min. (a) Determine the induced emf in the alternator as a function of time. (Assume & is in V.) 8 = 1.21 sin (wt) x (b) Determine the maximum emf in the alternator. 1.21 X What are the maximum values of the sine and cosine functions? V Need Help? Read It Watch It
