Hi All
Must admit I am finding transistor circuits pretty difficult to grasp right now so I would really appreciate some help here.
Attached are 3 pictures:
1. Circuit diagram of unstablized transistor circuit.
2. Close-up graphic of a "heating resistor" (whatever that is?).
3. Photo of my attempt at wiring the circuit on a trainer breadboard.
My questions:
1. Have I wired the trainer breadboard correctly?
2. Can someone please explain how I am meant to wire in the "heating resistor" and what role it plays in the circuit?
3. Please describe the electron flow.
My attemp:
1. See the attached photo of the wired circuit on the trainer breadboard. I did that.
2. Really confused with the "heating resistor". Is it meant to touch the transistor to keep it "cool"? Why is it wired with solder? Is that so you can bend it over to touch the transistor?
3. Electron flow:
Starting at yellow -10V the electron flow goes through R1, then collector, then base, then R2, then 2 on 1k POT, then from POT to who knows? Stuck here. Help.
At the same time the electron flow goes through the Emitter, then to Ground, then 1 on 1k POT, then from POT to who knows?
It seems that when the flow goes into either 1 or 2 on the 1k POT it then flows back to -10V??? Confused here, how would it go back to where it started? Negative is not attracted to negative, but it looks that way...
And I would guess the "heating resistor" would be wired to the red +15v and to ground, and is there to "cool" the transistor when it is bent over to touch it?
I know there are 3 questions here so I am really hoping to get 3 answers. Any help appreciated.
