Question

A parallel resonant circuit has a midband admittance of 20×10^-3 S, quality factor of 60 and a resonance frequency of 200 k rad/s. The value of R is _____________ (a) 50 Ω (b) 56.57 Ω (c) 80 Ω (d) 28.28 Ω I got this question in semester exam.

Answer 1

Correct option is (a) 50 Ω To explain I would say: At midband frequency, Z = R, Y = \frac{1}{R} Or, R = \frac{1}{20 × 10^{-3}} = 50 Ω.
