Machine sensing, where the alternator output voltage is used to vary the current in the rotor windings, is a method of controlling

Homework Help
  1. The function of the heat sink part of the rectifier diode pack in an alternator is to:
    (a) Conduct heat away from the diodes in order to protect them
    (b) Provide a solid base for the transistors
    (c) Act as a voltage regulator
    (d) Prevent the stator from overheating.

    2. Machine sensing, where the alternator output voltage is used to vary the current in the rotor windings, is a method of controlling:
    (a) The phase angle of the a.c. output
    (b) The voltage output of the alternator
    (c) The self-exciting voltage of the alternator
    (d) The brush pressure on the slip rings.

    3. A slack alternator drive belt may cause the:
    (a) Engine to overheat
    (b) Engine to lose speed
    (c) Battery to become discharged
    (d) Charging rate to be too high.
