GATE EC 2023 Set 1 Q42 — Transmission Lines

The standing wave ratio on a $50 \; \Omega$ lossless transmission line terminated in an unknown load impedance is found to be $2.0$ . The distance between successive voltage minima is $30 \mathrm{~cm}$ and the first minimum is located at $10 \mathrm{~cm}$ from the load. $Z_L$ can be replaced by an equivalent length $l_m$ and terminating resistance $R_m$ of the same line. The value of $R_m$ and $l_m$ , respectively, are

A $50 \Omega$ lossless transmission line is terminated with a load $\mathrm{Z}_{\mathrm{L}}$ of $(50-\mathrm{j} 75) \Omega$ . If the average incident power on the line is $10 \: \mathrm{mW}$ , then the average power delivered to the load (in $\mathrm{mW}$ , rounded off to one decimal place) is $\_\_\_\_\_\_\_$ .
