First find fr = 1/6.28 times square root of LC.
You will got 71.2 hz.
Then find xl = 6.28 times fl you will got 2.23 k if xl = xc.
Then q = xl/r you will got 2.23 k/1 k = 2.235.
If the formula for bw = fr/q.
fr = 71.2 and q = 2.235 so bw = fr/q will be equals to 31.8 hz.
You will got 71.2 hz.
Then find xl = 6.28 times fl you will got 2.23 k if xl = xc.
Then q = xl/r you will got 2.23 k/1 k = 2.235.
If the formula for bw = fr/q.
fr = 71.2 and q = 2.235 so bw = fr/q will be equals to 31.8 hz.

Q=(omega*L)/R.
BW=f/Q,
=> BW=(f*R)/(w*L)
=> BW=R/(2*pi*L)
=> Bw=31.8.
BW=f/Q,
=> BW=(f*R)/(w*L)
=> BW=R/(2*pi*L)
=> Bw=31.8.

Easy way.
BW = Fr/Q
BW = 1/2*pi*L/R
BW = R/2*pi*L
BW = 31.83
BW = Fr/Q
BW = 1/2*pi*L/R
BW = R/2*pi*L
BW = 31.83

Bandwidth= R/(2*L)...Hz.
= 1000/(2*3.14*5).
= 31.84 Hz.
= 1000/(2*3.14*5).
= 31.84 Hz.

Here, R/(2*π*L) = 31.8.

Q=XL/R.
BW=fr/Q.
fr=1/2*pi*√LC=71.17.
XL=WL=2235.87,
Q=XL/R=2.23.
B=71.17/2.23=31.83.
BW=fr/Q.
fr=1/2*pi*√LC=71.17.
XL=WL=2235.87,
Q=XL/R=2.23.
B=71.17/2.23=31.83.

The bandwidth formula can be rearranged to R/(2*π*L).

fr = QBW.
BW = fr/Q.
fr = 1/2π √LC..
Q=(1/R)(√ of L/C).
BW = fr/Q.
fr = 1/2π √LC..
Q=(1/R)(√ of L/C).

As Q=B.W/fr
so fr=1/(2pie*underroot of LC)
And Q=UNDERROOT OF L/(R*UNDERROOT OF C)
B.W=?
so fr=1/(2pie*underroot of LC)
And Q=UNDERROOT OF L/(R*UNDERROOT OF C)
B.W=?

B' = R/L in radians.
B' = 1000/5.
B' = 200.
B = B'/2*pi.
B = 200/2*pi.
B = 31.83.
B' = 1000/5.
B' = 200.
B = B'/2*pi.
B = 200/2*pi.
B = 31.83.
