Answer: 30 ohms, 1000 V
The bandwidth formula for the series rlc circuit is B.W=R/L.
Bandwidth is generally defined as a band of frequencies a circuit passes or rejects.
The bandwidth of the rlc circuit is defined as the range of frequencies for which circuit output voltage (or) current value equals 70.7 % of its maximum amplitude, which will occur at the resonant frequency.
The bandwidth formula for the series rlc circuit is B.W=R/L
Resonant frequency ωr=3000 rad/sec,
Excitation (or) input voltage V=100 V,
Bandwidth B.W=300 rad/sec,
Inductance L=0.1 H,
As we know, B.W=RL=300 rad/sec
Under resonant condition XL=XC
Current through series resonant circuit I=V/Z=V/R=100/30 =10/3
And voltage across capacitor VC=IXC=I(1/ωC)=(10/3)(1/3000(1.111 μF))=1000 V.
