Answer published by the source. Consult the official source to check your work against its answer.
question
At a frequency of 4000 kilocycles a parallel-wire transmission line has the following parameters: R = 0.025 ohm/m, L = 2 \muh/m, G = 0, C = 5.56 \mu\muf/m. The line is 100 meters long, terminated in a resistance of 300 ohms. Find the efficiency of transmission, defined as the ratio of the power delivered to the load to the power supplied to the input terminals.
