Characteristic impedance of a transmission line is 50 Ω. Input impedance of the open circuited line.
Zoc = 100 + J150 Ω. When transmission line is short circuited, then value of the input impedance will be
[A]. 50 Ω
[B]. 100 + J150 Ω
[C]. 7.69 + J11.54Ω
[D]. 7.69 - J11.54 Ω

Answer: Option D

Explanation:

√ZC = ZOC - ZSC 1-sym-imp50 = (√100 + j150)(ZSC) .
