  • Question

  • Characteristic impedance of a transmission line is 50 ?. Input impedance of the open circuited line.
    Zoc = 100 + J150 ?. When transmission line is short circuited, then value of the input impedance will be


  • Options
  • A. 50 ?
  • B. 100 + J150 ?
  • C. 7.69 + J11.54?
  • D. 7.69 - J11.54 ?

  • Correct Answer
  • 7.69 - J11.54 ? 

    Explanation
    ZC = ZOC - ZSC ⟹ 50 = (100 + j150)(ZSC) .
