5, -2 points self SET9 31P045 My Notes o Ask Your Tescher In a 290-turn automobile alternator, the magnetic flux in cach turn is 4B 2.50 x 10-4 cos at, where B is in wcbcrs. a is the angular spced of the altcrnator, and t is in seconds. The alternator is gcared to rotate five times for cach cnginc revolution. The engine is running at an angular speed of 1,00 x 103 revymin. (a) Determine the induced emf in the alternator as a function of time. (Assumc E is in v) Need Help? Rend
