Q. The range of characteristics impedance for co-axial wire lines is
A) $40\ \Omega\ to\ 150\ \Omega$
B) $400\ \Omega\ to\ 1500\ \Omega$
C) $4\ \Omega\ to\ 15\ \Omega$
D) $40\ k\Omega\ to\ 150\ k\Omega$
Explanation
(a) Characteristic impedance $(Z_{0})$ of a co-axial wire line is lower $ie$, from 40 to 15$\Omega$
