1.	The characteristic impedance of the line having primary constants L and C as 35 milli henry and 70 micro farad respectively is(a) 500(b) 22.36(c) 125(d) 50This question was addressed to me in final exam.The origin of the question is Lossless and Distortionless Line topic in portion Transmission Lines of Electromagnetic Theory
Answer» Correct answer is (B) 22.36 To explain: The characteristic impedance of a lossless line is given by Zo = √(L/C). On substituting for L = 35 X 10^-3 and C = 70 x 10^-6, we get Zo = √(500) = 22. 36 ohm.
