To reduce the resonant frequency in an LCR series circuit with a generator

Question

To reduce the resonant frequency in an LCR series circuit with a generator (A) the generator frequency should be reduced (B) another capacitor should be added in parallel to the first (C) the iron core of the inductor should be removed (D) dielectric in the capacitor should be removed

Resonant frequency in a series LCR circuit is upsilonr=(1/2π√LC) If capacitance C increases the resonant frequency will reduce, which can be achieved by adding another capacitor in parallel to the first.

Q. To reduce the resonant frequency in an $L CR$ series circuit with a generator

the generator frequency should be reduced

another capacitor should be added in parallel to the first

the iron core of the inductor should be removed

dielectric in the capacitor should be removed

Resonant frequency in a series $L CR$ circuit is
$υ_{r} = \frac{1}{2 π L C}$
If capacitance $C$ increases the resonant frequency will reduce, which can be achieved by adding another capacitor in parallel to the first.
