The q of a coil is independent of frequency
Webb8 apr. 2024 · Mathematically, the Q-factor is given by: Q = ω o L R = X L R It is also defined in terms of Bandwidth, i.e. Q = f r B W Where, fr = Center frequency of the filter or the resonant frequency. BW = Bandwidth Calculation: Given: R = 5Ω, L = 1 μH f 0 = 1 Mhz Q = ω o L R = 2 π f 0 L R On solving we'll get: Q = 1.256 Hence, Option D is correct.
