  • Question

  • The input impedance of short-circuited line of length l where ?/4 < l < ?/2, is


  • Options
  • A. resistive
  • B. inductive
  • C. capacitive
  • D. none of the above

  • Correct Answer
  • capacitive 

    Explanation
    l < ?/4, ZL = 0

    The input impedance of short-circuited line of length l where ?/4 < l < ?/2, is resistive inductive , if Zd comes +j kZC then inductive,

    If Zd comes -j kZC then capacitive.

    for 0 ? l ? 1/4, ? ? l ? 3?/4 will be inductive.

    The input impedance of short-circuited line of length l where ?/4 < l < ?/2, is resistive inductive
