1.	The propagation constant of a transmission line with impedance and admittance of 9 and 16 respectively is(a) 25(b) 144(c) 12(d) 7I had been asked this question during an online exam.I'm obligated to ask this question of Transmission Line Primary Parameters topic in division Transmission Lines of Electromagnetic Theory
Answer» Correct option is (c) 12 Best explanation: The propagation constant is GIVEN by γ = √(ZY), where Z is given by 9 and Y is 16. On substituting the given values, the propagation constant will be γ = √(ZY) = √(9 x 16) = 12 units.
