Multiple choice

Characteristic impedance of a transmission line is 50$\Omega$. Input impedance of the open circuited line is Zoc = 100 + j150$\Omega$. When the transmission line is short-circuited, the value of the input impedance will be

  1. 50 $\Omega$
  2. 100 + j150 $\Omega$
  3. 7.69 + j11.54 $\Omega$
  4. 7.69 - j11.54 $\Omega$
