For a series RLC circuit, the quality factor is defined as the ratio of
Right Answer is:
Resonance frequency to bandwidth
SOLUTION
The quality factor Q is defined as the ratio of the resonant frequency to the bandwidth.
Q = fr/BW
fr = resonant frequency
For a series RLC circuit, the resonance frequency is calculated as:
${f_r} = dfrac{1}{{sqrt {LC} }}$
The bandwidth of a series RLC circuit is calculated as:
BW = R/L
substituting this in Equation
$Q = dfrac{{{f_r}}}{{BW}} = dfrac{1}{R}sqrt {dfrac{L}{C}}$
