Its rad  :trouble

I got pretty excited looking at H. Then I looked at the others and got even more excited.

Its like the ten commandments of transistors

Looks very good and Sams is a very good no nonsense Tech book Company.

Maybe there is a downloadable version somewhere?

I am too far away to order a paper copy.

Thank you sir I can probably send you this one if you like  :tu:

I'm not a big seller on the bay but I have sold a few things lmk I will be glad to do it gratis of course.

I did skim through the content a bit one thing I noticed he likes making a voltmeter lead with a small capacitor in series

Thanks A LOT.
It is VERY kind of you.
Sadly I am way too far away, 5000mi-8000km away as the crow flies.
And it would become a VERY tired crow  :lmao:



But again, thanks A LOT for your kindness.

Take care Friend.

Mucho gracias hermano  <3)

All of this reminded me of my dad and two gringo (mucho barracho) buddies drove a car to Costa Rica.
I had a lot going on at the time and chose not to even try and wrap my head around it I simply told him "ok yeah well you'll never be seen again"

:loco

They completed the trip which purpose was to deliver a car 🚗 and returned.  He had hours of VHS camcorder footage including several instances of military 🎖�🪖 instructing him to put the camera away.  xP

He was lucky.
Ruffling military´s feathers the wrong way isn´t healthy anywhere in the World  :o

This is a great book 📖

I just made a pretty big step forward trying to comprehend all this stuff when this book pointed out that the collector-base junction of a transistor is in zener mode when conducting :dbtu:

Idk why I couldn't get past thinking it had to be forward biased ie pointing the same way as the base-emitter junction

So then I was thinking ok well all we have to do is increase collector voltage to get it to work but then I was like aahh ok yeah that's where the role of the base come in.   xP


As a technical aside he points out that many a transitor has been installed incorrectly and it might "work" to some degree but problems will remain  :grr

I was also glad to see (because I wondered about it) is that regardless of a transistor in the loop Kirchhoff's law still applies  :trouble

For instance start at Vcc go through collector resistor then through transistor then through emitter resistor or whatever all the way to ground the voltage drops have to add up and the same for starting at the voltage headed to the base  :tu:

Something else that was bugging me  :dbtu:

So I drew a picture to describe

Yeah I know...go look it up  xP

Ok nevermind I think it is parallel if we consider the emitter to be the node... possibly

So the voltage drops across the resistor and bipolar junction on each side have to equal each other 🙏
