...but I don't really grok the transistor yet.... it seems like my brain isn't as agile or adept as it was back in the 80's, when first studied electronics. One thing I was wondering, just the other day, was if there's a wall chart... I'm not sure exactly sure what I'd expect to find, but I figure there are some basic rules and characteristics which could be expressed.(But I'm really visually oriented, so a poster would be really cool.)
After 30 years, man, it's like... well, hope springs eternal.So, here's a "poster" (Take this, may it serve you well) ?
(although the posting I originally referred to is about how/why transistors WORK, internally as a semiconductor, not about how they BEHAVE in circuits.)
If i am not pulling anything out of the base i have those two darned depletion layers in the way that prevent current from flowing. if i start pulling some electrons out of the base the depletion area is being broken down
If you read mine attentively you will see that i never use the word 'base current'. It is the voltage difference ( potential) that causes the electrons to flow , and the electrons are charge carriers. it i indeed the pressure ( the 'voltage' , technical definition 'potential' that cases charge to move ) i control the direction it is allowed to flow by applying pressure ( or void thereof ) to the base
