DC series motors are used _______________(a) Where load is constant(b)

1.	DC series motors are used _______________(a) Where load is constant(b) Where load changes frequently(c) Where constant operating speed is needed(d) High starting speedThis question was addressed to me in an online interview.My question is taken from Operating Characteristics of DC Series Motor -1 in portion Characteristics of DC Motors of DC Machines
Answer» The correct answer is (d) High STARTING speed Explanation: DC series MOTORS are USED in those APPLICATIONS where high starting speed is REQUIRED at its initial phase. Since no load operation speed of DC series motor is very high, it is always operated on some non-zero load.
