An ac generator consists of 100 loops of wire,each of area 0.090 m²,and has a total resistance 12 Ω.The loops rotate about a diameter in a magnetic field of 0.50 T at a constant angular speed of 60 revolutions per second.Find the maximum induced emf in the generator. A)0.27 kV B)0.54 kV C)1.7 kV D)3.4 kV

Question

Quizplus · Accepted Answer

The maximum induced emf in the generator can be calculated using the formula:

Emax = NABω

where N is the number of loops, A is the area of each loop, B is the magnetic field strength, and ω is the angular speed.

Substituting the given values, we get:

Emax = (100)(0.090 m²)(0.50 T)(2π(60 rev/s))

Emax = 1.7 kV

Therefore, the correct choice is C, with a maximum induced emf of 1.7 kV.
