A)3.4 V
B)110 V
C)43.2 V
D)21.3 V
E)55.4 V

Question

Quizplus · Accepted Answer

The peak voltage generated in a coil rotating in a magnetic field can be found using the equation:

Vp = 2πfNAB

Where f is the frequency of rotation, N is the number of turns in the coil, A is the area of the coil, and B is the strength of the magnetic field.

Substituting the given values, we get:

Vp = 2π(60)(68)(0.054)(0.04)(0.78)

Vp ≈ 43.2 V

Therefore, the correct answer is (C) 43.2 V.
