Question

Quality factor Q of a series LCR circuit is:
  1. A
    ω₀L/R
    Correct
  2. B
    R/ω₀L
  3. C
    ω₀C/R
  4. D
    ω₀/(RC)

Correct answer

ω₀L/R

Explanation

Q = ω₀L/R = 1/(ω₀CR) = (1/R)√(L/C). Higher Q means sharper resonance peak and lower bandwidth. Q is also the ratio of energy stored to energy dissipated per cycle.
