Q. The characteristic impedance $(Z_{0})$ parallel line wire is
A) $Z_{0} = \frac{276}{\sqrt{k}}\log\frac{2s}{d}$
B) $Z_{0} = \frac{376}{\sqrt{k}}\log\frac{2s}{d}$
C) $Z_{0} = \frac{276}{k}\log\frac{2s}{d}$
D) $Z_{0} = \frac{276}{\sqrt{k}}\log\frac{d}{2s}$
Explanation
(a) Choice (a) is correct as $Z_{a} = \frac{276}{\sqrt{k}}\log\frac{2s}{d}$
