Solution

Bandwidth(BW)=f2-f1;

were f1 is the frequency at which the current is 0.707 times the current at resonent value, and is called the lowercut off frequency.

the frequency f2 is the frequency at which the current is 0.707 times the current at resonantvalue(i.e maximum value).

and is called upper cutoff frequency.

f2-f1=R/(2*pi*L) =1500/(2*3.14*0.210) = 1137.39 Hz

resonent frequency (fr) =1/[2*pi*sqrt(LC)]
