QJEEM22Phecd5: JEE Main 2022 Physics - Class 12 JEEM22Phecd5 Solution: To increase the resonant frequency in series LCR circuit,

To increase the resonant frequency in series LCR circuit,

Multiple Choice Options

  • A source frequency should be increased.
  • B another resistance should be added in series with the first resistance.
  • C another capacitor should be added in series with the first capacitor.
  • D the source frequency should be decreased.

Step-by-Step Verified Solution

Resonant frequency =1LC=ω0= {1 \over {\sqrt {LC} }} = {\omega _0}

⇒\Rightarrow If we decrease C, ω\omega 0 would increase

⇒\Rightarrow Another capacitor should be added in series.
