Easy MCQ +4 / -1 PYQ · JEE Mains 2022

To increase the resonant frequency in series LCR circuit,

  1. A source frequency should be increased.
  2. B another resistance should be added in series with the first resistance.
  3. C another capacitor should be added in series with the first capacitor. Correct answer
  4. D the source frequency should be decreased.

Solution

<p>Resonant frequency $= {1 \over {\sqrt {LC} }} = {\omega _0}$</p> <p>$\Rightarrow$ If we decrease C, $\omega$<sub>0</sub> would increase</p> <p>$\Rightarrow$ Another capacitor should be added in series.</p>
