Electromagnetic Field Theory
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
50 Ω
100 + J150 Ω
7.69 + J11.54Ω
7.69 - J11.54 Ω
Correct Answer:
7.69 - J11.54 Ω
Explanation:
