Academics

An AC generator is to have a maximum output of 318 V. Each coil has an area of 0.145 m2 and a resistance of 15.7 ? and rotates in a magnetic field of 0.722 T with a frequency of 41.8 Hz, with the axis of rotation perpendicular to the direction of the magnetic field.

(a) How many turns of wire should the coil have to produce the desired emf?

N = turns

(b) Find the maximum current induced in the coil.

Imax = A

= ( V)sin t
