Hi everyone,
Im looking for help on how to set up an experiment to view the current flow of parallel resonance with an oscilloscope.
My resonate setup is the same as the example on http://www.falstad.com/circuit/e-res-par.html (or attached image)
Im using a 0-50 mhz sin/tri/sqr wave generator and the same components as in the example. 40.1hz, 1R, 1H, .15u
What would be the best way to view the current and voltages flowing back and forth between the coil and the capacitor?
In the example, the resonance seems to be nailed to 40.1 hz and any deviation causes the example to change noticeably. In my experiment, I put a 10k resistor in series with the coil and the capacitor and thought Id measure the voltage drop across it. However, the scope image doesnt seem to change much as I alter the frequency unless I go really far off the resonant frequency.
Also I dont see much change in the signal when I alter the inductance. (Ive made a variable inductor, .5H to .998H)
Im sure Im just unfamiliar with how to set this all up. Any help would be appreciated.
Thanks in advance, Herb
