In a series$LCR$ circuit, the inductance$L$ is $10 \mathrm{mH}$, capacitance $C$ is $1 \mathrm{\mu F}$ and resistance $R$ is $100 \mathrm{\Omega }$. The frequency at which resonance occurs is:

• Correct answer
  A

  $1.59 \mathrm{kHz}$
• B

  $15.9 \mathrm{rad} {\mathrm{s}}^{-1}$
• C

  $15.9 \mathrm{kHz}$
• D

  $1.59 \mathrm{rad} {\mathrm{s}}^{-1}$

Hence, the correct answer is option: 'A'.
