Hello Experts,
i just read the topic "Base Bias" from Floyd..
am confused for its application that why this topic is included in this book.
because its application and practical use is not mentioned here.

so i google it and find many result for its equation but didnt find the application.:confused:

secondly its talk about Q-point stability...
what does its means..
its equation shows that Ic is dependent on βdc , so change in βdc causes Ic and thus change in Q point of transistor..

Please Explain it,

Thank you.
