Question

A lossless transmission line has a shunt capacitance of 10 pf/m and a series inductance of 4microhz/m.what is it's characteristics impedance

Answer 1

At a frequency of 4 MHz a parallel wire transmission line has the following parameters: R = 0.025 Ω/m, L = 2 μH/m, G = 0, C = 5.56 pF/m. The line is 100 ...

Answer 2

A lossless transmission line has a shunt capacitance of 10 pf/m and a series inductance of 4microhz/m. 1.58 is it's characteristics impedance

Explanation:

The Standard International unit of characteristics Impedance is in ohmΩ.

The characteristics of lossless transmission lines are 100% real and also have no reactive component.

The energy which is supplied by a source at an end of such line is transmitted through the line without dissipation in the line.

Formula

Characteristics impedance of lossless transmission is given by $\sqrt{\frac{L}{C} }$.

$\sqrt{\frac{L}{C} } = \sqrt{\frac{10}{4} } = \sqrt{2.5} = 1.58$

Therefore, a lossless transmission line has a shunt capacitance of 10 pf/m and a series inductance of 4microhz/m. 1.58 is it's characteristics impedance.
