A lossless coaxial cable has a capacitance of ` 7 xx 10^(-11)F` and inductance of 0.39 `muH`. The characteristic impedance of the cable is

Text Solution

Verified by Experts

Here, `C=7xx10^(-11)F`, `L=0.39xx10^(-6)H,Z_(0)`=?, As the cable is loseless, `therefore Z_(0)sqrt((L)/(C))=sqrt ((0.39xx10^(-6))/(7xx10)^(-11))=75ohm`
