Physics - EMI/AC Question with Solution | TestHub

Here${\text{L}}_{\text{eq}}=\text{L}+2\text{L}=3\text{L}$(in series)

${\text{C}}_{\text{eq}}=\text{C}+2\text{C}=3\text{C}$(in parallel)

$\omega =\frac{1}{\sqrt{{\text{L}}_{\text{eq}}{\text{C}}_{\text{eq}}}}$

$=\frac{1}{3\sqrt{\text{LC}}}$

frequency$f=\frac{\omega }{2\pi }=\frac{1}{6\pi \sqrt{\text{LC}}}$
