$Q}_{\text{S}}\text{\hspace{0.05em}}\text{\hspace{0.05em}}=\text{\hspace{0.05em}}\text{\hspace{0.05em}}\frac{{\omega}_{\text{r}}{L}_{1}}{{R}_{1}$

where

$\omega}_{\text{r}}\text{\hspace{0.05em}}\text{\hspace{0.05em}}=\text{\hspace{0.05em}}\text{\hspace{0.05em}}\text{\hspace{0.05em}}\text{\hspace{0.05em}}2\pi \text{\hspace{0.05em}}\text{\hspace{0.05em}}{f}_{\text{r}$ is the angular resonance frequency;

*f*_{r} _{} is the resonance frequency;

*L*_{1} is the motional inductance;

*R*_{1} is the motional resistance
