Physics - Capacitor Question with Solution | TestHub

The circuit shown is a parallel resonant circuit. The frequency is $\mathrm{f}=\frac{1}{2\pi \sqrt{\mathrm{LC}}}$ at resonance. Also, at resonance, the capacitative reactance is equal to the inductive reactance. Therefore, equal current will flow through both the bulbs ${\mathrm{b}}_1$ and ${\mathrm{b}}_2$. So, both will glow with same brightness.
