SUMMARY

This discussion focuses on connecting an oscillator, capacitor, and resistor in series on a breadboard. The user describes wiring the positive terminal of the oscillator to the capacitor and resistor, with a ground reference established. They detail their setup using specific bus connections, indicating a positive voltage on bus 5 and a negative connection on bus 7. The conversation emphasizes the safety features of modern function generators, which provide protection against potential mistakes during initial setups.

I want to build a circuit consisting of an oscillator, capacitor, and resistor connected in series. I've never used a breadboard before though, and I want to make sure nothing goes wrong.

From what I understand, I need to wire the +ve of the oscillator in series with the capacitor and resistor. Then connect a reference to ground. I drew what I think this would look like in the image below:

So I have the +ve wired along bus 5 supplying power to the capacitor connected across a5 and c5. I then hook up the resistor along d5 so it is in series with the capacitor and create a short to d7. The -ve is located along bus 7.

This would work I hope.

Wow my first attempt was terrible. I have a new attempt that should actually work now I think:

That's right. If your current source is any sort of modern function generator you shouldn't worry too much about just hooking it up and seeing if it works. Function generators usually have a breaker and other built-in protection that'll keep you from burning them up if you make a mistake, as long as you aren't doing anything crazy.
 
Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
