MCQ
A motor starter
  • A
    Is a variable resistor
  • B
    Offsets the back $emf$ variations
  • C
    Helps start a $DC$ motor
  • All of these

Answer

Correct option: D.
All of these
d
(d)

starting resisted are used in high power $D)$ ( motes, before we had variable frequent $A C$ motor drive, high power $D C$ motors were compos. Starting ngistors are used to limit starting cessent. Therefore they of sets back emt mosiations so answer is all of these.
