The magnitude of open circuit and short circuit input impedances of a transmission line are 100 Ω and 25 Ω respectively the characteristic impedance of the line is—
-
- 25 Ω
- 50 Ω
- 75 Ω
- 100 Ω
Correct Option: B
Characteristic impedance is given in terms of short circuit and open circuit impedance Zc =√ZSCZOC = √25 × 100 = √2500 = 50Ω
