Somebody told me that we are not able to use even 2 similar transistors for some works BECAUSE their Beta Is not completely similar (I.e the company is not able to produce 2 transistors with the same Beta even if they have the same mark).
Now that I am thinking about it A question arrases,
Here's the question:
Beta is Ic/Ib that means beta is the ratio between collector current and the base current, we identify those currents by the biasing resistors at the collector and the base so why the beta depends on the transistor itself?
For instance if 2 similar marked transistors have a beta rated at 400 by company (no matter if one has a beta more than that value) why we are not able to get the same results if we bias the collector and base resistors so that both the similar transistors give us the same response?
Make sense?
