1.	Which of the following is not an advantage of the alternator?(a) Higher output(b) Lower weight(c) Less maintenance(d) High efficiencyI have been asked this question in a job interview.This question is from Charging System topic in portion Nonconventional Engines, Conventional Energy Sources & Cooling System of Automobile Engineering
Answer» The correct answer is (d) HIGH EFFICIENCY Best EXPLANATION: With a lightweight of the ALTERNATOR, the efficiency of alternator increases. As the OUTPUT current does not flow through the commutator and brushes, thus surface contamination is eliminated.
