This is a proper training video! All who want to show how to use an electrical device should watch this first. I would love to see this one extended with the math exercise to go along with it.
OK, So.... NPN - B-C-E .... so Neg-B Pos-C Neg-E .... OFF PNP - B-C-E .... so Pos-B Neg-C Pos-E .... OFF Arrow always on Emitter side. Load always on Emitter or Collector side? (seems different videos suggest placing load at different locations...?) Change polarity of Base to turn ON Thanks
The problem I see with this example is that the base of the 2n2222 does not have a current limiting resistor. The total voltage drop is across the base emitter junction, that junction is only dropping .7v. So there is no resister to limit the current at the base of his circuit. He will burn the transistor out using it this way. This is a poor example. Neither does he tell us, what the voltage that is being applied. If you are going to teach electronics, show schematic of the circuit being used as a demo.
Mr. Schulz covers transistors in the most easily understood manner of so many online teachers. He is a master of his subject.

Thank you for the one stop understanding of transistor including theory and application...
Thank you. i was trying to figer out 3 days but you explane it perfect i will keep this video like a usefull book .

Thanks
Very clearly explained! Thanks
Thank you. Nicely explained.
Thanks!
great video!!
what if i connect the load across the emitter of the transistor?
will that work?
