A generator rotates at 91 Hz in a magnetic field of 0.050 T . It has 750 turns and produces an rms voltage of 130 V and an rms current of 45.0 A . What is the peak current produced? Express your answer to three significant figures and include the appropriate units. What is the area of each turn of the coil? Express your answer to two significant figures and include the appropriate units.
Homework Answers
a)
peak current
io = i rms * sqrt (2) = 63.6 A
=======
b)
peak emf is given by
Vrms * sqrt(2) = N B A ( 2 pi f)
130* 1.414 = 50* 0.05* A * ( 2* 3.14* 91)
A = 0.129 m^2
