Lossless, Distortionless & Low Loss Transmission Line

The character...

Question

The characteristic impedance of a certain loss less transmission line is $72 Ω$ . If $L = 0.5 μ H / m$ . then the value of C (in pF/m) is _________ .

Open in App

Solution

$C = \frac{L}{Z_{0}^{2}} = \frac{5 \times 10^{- 7}}{(72)^{2}} = 9.6 \times 10^{- 11} F / m = 96 p F / m$
