Question

In L C R circuit current resonant frequency is 600 Hz and half power points are at 650 and 550 Hz. The quality factor is (A) (1/6) (B) (1/3) (C) 6 (D) 3

Quality factor =(f0/f2-f1)=(600/650-550) =(600/100)=6

Q. In $L CR$ circuit current resonant frequency is $600 Hz$ and half power points are at $650$ and $550 Hz$ . The quality factor is

$\frac{1}{6}$

$\frac{1}{3}$

$6$

Quality factor
$= \frac{f _{0}}{f _{2} - f _{1}} = \frac{600}{650 - 550}$
$= \frac{600}{100} = 6$
