Question

The capacitance per unit length and the characteristic impedance of a lossless transmission line are C and $Z_0$ respectively. The velocity of a travelling wave on the transmission line is

Answer 1

Ans : (b)

$Z_0=\sqrt{\frac{L}{C}}$

$Z_0^2=\frac{L}{C}$

$L=Z_0^{2}C$

$v=\frac{1}{\sqrt{LC}}=\frac{1}{\sqrt{\left(Z_0^{2}C\right)\left(C\right)}}=\frac{1}{Z_{0}C}$
