The lab exercise: A resonant circuit which amplifies a small 20kHz input voltage at least 20 times.
I've been quite stumped on this one for a while now. I basically started out with the components I have on hand 1kΩ resistor; 33mH inductor; and then calculated the needed capacitance (1/4π²f²L) based on those and the resonant frequency needed, and I got 1.92nF.
I have these set up in series, and set the generator to 20kHz, with scopes across the supply, and one on the resistor. The supply scope is reads 4.2V and the resistor reads 2.48V.
Do I have this set up correctly? If so why am I getting a higher voltage on the supply? Should I put one of the scopes across either the inductor or capacitor? I'm really unsure how to go about this.
I appreciate your help in advance.
