Hi all.
I am currently building a series RLC circuit as a magnetic field transmitter. Because I want to have a strong magnetic field, I need high voltage by making the circuit at resonance.
Here are the parameter I used:
L:1.15mH
R: 50 (internal resistance from functional generator )+ 0.58 (from inductor)
C: 1 nf.
Using equation the equations w0=1/sqrt(LC), and Vc= Q Vs= 1/R*sqrt(L/C)*vs,
w0=148kHz, and Q=21.2V, and Vs=5V(square wave), so voltage across capacitor should be around 108 V rms.
But using the oscilloscope, the V pk-pk voltage measured is only about 60 V, Vmax is about 20V.
So, why am I not getting the calculated result?
