An LCR series circuit is connected to an oscillator (AC supply) having RMS voltage $200\mathrm{ }\mathrm{V}$. If the RMS voltages across resistor, inductor and capacitor are equal, then RMS voltage across the resistor would be

• A

  $100\mathrm{ }\mathrm{V}$
• B

  $\frac{200\mathrm{ }\mathrm{V}}{\sqrt{2}}$
• Correct answer
  C

  $200\mathrm{ }\mathrm{V}$
• D

  $\frac{100}{\sqrt{2}}\mathrm{V}$

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