1.	Buses, trains, trolleys, hoists, cranes make use of DC series motor because __________(a) It provides low starting torque(b) Cost efficient(c) It provides high starting torque(d) It requires minimum power compare to other motorsI got this question in an online quiz.My enquiry is from Operating Characteristics of DC Series Motor in division Characteristics of DC Motors of DC Machines
Answer» The correct answer is (C) It provides high starting torque For EXPLANATION I would say: DC series motor provides very high starting torque, and at higher TORQUES speed of the DC series motor is ALSO maintained to constant. Both of these properties are used in applications of DC series motor.
