resonance in a LCR series - Click HERE for Original Thread
Helix
URGENT HELP REQUIRED!

I have a LCR series circuit, i have the following problem finding the Q.
F=resonant req
B=bandwidth


I thought the Q = F/B

where B = R/(2*pi*L)

my inductor is 68mH
capacitor = 2.2uF
Resistor = 100Ohm

so i found resonance at 411 Hz

But i calculate Q to be 1.75? shouldn't it be about 0.7?

sorted!
i fergot to add the DC resistance of the inductor (it's about 150ohms or so), perhaps it's time for another cup of coffee!
