For two-phase AC servomotor, if the rotor’s resistance and reactance are respectively R and X, its length and diameter are respectively L and D then,
  • a)
    X/R and L/D are both small
  • b)
    X/R is large but L/D is small
  • c)
    X/R is small but L/D is large
  • d)
    X/R and L/D are both large
Correct answer is option 'C'. Can you explain this answer?
