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?
