Homework Statement
The scheme is here: http://img196.imageshack.us/img196/9366/lcre.jpg
G generates soundwaves, Re are all 10 ohm resistors , R is an 98000 active resistor, L=100mH, C=0.253 μF
The assignment was to measure the voltage through different parts of the circuit near resonance frequency and draw some graphs, but that's not the issue here.
When calculating the active resistance from the formula
R=Q/sqrt(C/L),
where Q is the Q-factor, the result is ~8900 ohms. This answer is correct and supposed to be so, but I have to explain WHY is this 11 times less than in the active resistor and this is the problem here. Can anyone give me some good advice?
