pi15 Circuit is in resonance condition
Capacitance C=3.125*10^-8 F (Computed from resonant frequency)
p=i2r=v2/r=2
(50*50)/2=r=1250 ohms
Vl=(2*pi*f*L)*Il
50=(800*L*1.25*1000)
L=50microH
answer b
16 quality factor
Q =(R/(wL))
=1250/(800*50*10^-6*1000)=31.25
lower cut off frquency = wo-(bandwidth/2)=(800*1000)-(1/(2*R*C))=800-12.8=787.2Krad/s
Answer f
17
rms current =(V/R)
=50/1250=40mA
