Question: A coil of resistance R and inductance L is connected in series with 10 mF capacitor. The resonant frequency is 1000 Hz. Another 10 F capacitor is connected in parallel with the above capacitor. The new resonance frequency will be
[A].

1000 Hz

[B].

more than 1000 Hz

[C].

less than 1000 Hz

[D].

may be more or less than 10000 Hz

Answer: Option C

Explanation:

Total capacitance increases and therefore ωr decreases.
