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!
