The quality factor of LCR circuit having resistance (R) and inductance (L) at resonance frequency ($\mathrm{\omega }$ ) is given by 

• A

  $\frac{\mathrm{\omega L}}{\mathrm{R}}$

• B

  $\frac{\mathrm{R}}{\mathrm{\omega L}}$

• C

  ${\left(\frac{\mathrm{\omega L}}{\mathrm{R}}\right)}^{1/2}$

• D

  ${\left(\frac{\mathrm{\omega L}}{\mathrm{R}}\right)}^2$
