  • Question

  • The current rating of a cable depends on


  • Options
  • A. length of cable
  • B. diameter of cable
  • C. both length and diameter of cable
  • D. none of the above

  • Correct Answer
  • diameter of cable 

    Explanation
    Current rating depends only on area of cross-section and hence diameter.
