Heya Everyone
I decided to do some experiment with an LR circuit. I have an inductor in series with a resistor connected to a function generator. I will set the frequency to the resonant frequency of the circuit. Now, I will change the inductance of the inductor by bringing in a conductor close to the circuit. I would connect the voltage across the inductor to an oscilloscope to see the change in voltage.
What I am really interested in is to see how the frequency of the circuit changes as I bring the conductor close to the circuit. As the curcuit resonante at fundametal frequency- I expect to see a stright horizontal line in the frequency vs time graph. As the resonant frequency changes , I would expect some peaks in the graph. I understand the physics behind the circuit but totally lost on how to collect , save and then graph the frequency of the circuit. What equipment would I need ?
I believe some oscilloscope come with USB interface to a PC. I will probably buy that - still doesn't solve the problem of data logging. Can I somehow use the frequency data to obtain the inductance? Would be cool if I am able to do so
Thanks in advance :)
