Hello,
I have been studying transistors recently and have seen this a few times.
IE = (1 + β)IB ≈ βIB ≈ IC

What does the 1+B mean, where does the 1 come from?
Is it something glaringly obvious because I have missed it. It isn't written in the text, does that matter or is it one of those things that you just except.
Thanks
Simon

Hey, its almost christmas, yay!!!
