1.	To reduce the resonant frequency in an LCR series circuit with a generator,A. the frequency of the generator should be reducedB. another capacitor should be connected is parallel with the first capacitorC. the iron core of the inductor should be removedD. the dielectric in the capacitor should be removed
Answer» Correct Answer - B `f=1/(2pisqrt(LC))` `therefore` To reduce f either L or C or both has to be increased.
