Hello,
I am relatively new in the field of electronics (mathematician originally) and my budget is very limited.
The unique measure instrument I have is an old (but good) multimeter that can measure potential difference as small as 0.01 V,
resistance and intensity, both in AC and DC.
I am trying to obtain electronics parts by demounting PC and other apparatus. No problem in general for resistances, and also for capacitors in general. But for selfs, and some capacitors, I don't know what is the impedance. Even Worse, for diodes, transistors and OAmp, I have no idea of the characteristics of these components (in general there is something written on these components but I don't know how to use this).
What I need are good tricks (even if I need to provide some work) to obtain these data, hopefully with the only help of my multimeter. If I need to buy something, what is the cheaper solution (again, assuming some work of my own). There may exist some good link on this subject, which will be extremely welcome. thx.
