A small alternator is required to supply 230V rms at a frequency not exceeding 60Hz. The available design constraints are: magnetic field 0.30T and coil area 0.080m2.
a. (i) Determine the minimum whole-number of turns the coil should have to meet the voltage specification.
b. (ii) For this number of turns, calculate the rotational speed of the rotor in revolutions per minute (rpm).
