Question

The attenuation of a 50 ohm transmission line having a resistance of 100 ohm is

(a) 0.01

(b) 0.1

(c) 1

(d) 10

I had been asked this question in class test.

I'd like to ask this question from Transverse Electric Waves(TE) in section Waveguides of Electromagnetic Theory

Answer 1

Correct option is (c) 1

Explanation: The attenuation of a wave is given by α = R/2Z0. On substituting for R = 100 and Z0 = 50, we get α = 100/(2 x 50) = 1 unit.
