## Main Question or Discussion Point

I need help in answering the post lab questions given to us by our professor.

1. Is dc beta constant on every point of the characteristics? What is its effect in the linearity of the transistor?

2. What is the effect of a high dc beta on the characteristic curves?

I have attached an image of The bjt configuration.

Our data shows that dc beta isn't constant, but I can't see its effects in the linearity. I don't even know how to define linearity for a three terminal device like the BJT, but I guess that it must be based on Vce and Ic. Even if my guess is right, beta only relates Ib with Ic , and I can't think of any effects on linerarity and the characteristics.Applying KVL to the output side of the configuration produces a linear equation relating Vce and Ic. I can't really find an answer.

Please reply. Thanks in advance!!
