What is the Q factor for a 3-μH inductor with a total resistance of 4

1.	What is the Q factor for a 3-μH inductor with a total resistance of 45Ω at 90 MHz?(a) 37.68(b) 37.68Ω(c) 29.22Ω(d) 32.75ΩThis question was addressed to me in exam.I want to ask this question from Tuned Circuits in division Fundamentals of Electronics of Avionics
Answer» RIGHT choice is (a) 37.68 The best I can EXPLAIN: QUALITY FACTOR = Q = 2πfL/R = (2 x 3.14 x 90 x 10^6 x 3 x 10^-6)/45 = 1695.6 / 45 = 37.68.
