Physics Problem. EMF?
n ac generator has a circular coil of 88 turns and diameter 0.710 m which rotates about an axis in the plane of the coil and through its center. The coil rotates at 16.7 revolutions per second in a uniform magnetic field 0.050 T which is perpendicular to the axis of rotation.
What is the peak emf (in V) generated across the generator coil?
What is the rms emf (in V) generated?

ok, first of all we could look before everything condition a million. E=IR E=2R---------{a million} E=0.5(R+4)-------{2} you re so on the fringe of the respond. {a million}={2} 2R=0.5(R+4) R=4/3 now substitute R to {a million} equation E=2*4/3 E=8/3 V or 2.6666....V
