This channel is one of the best I've seen regarding teaching electronics theory. Worth its weight in gold! Thank you Ralph. 73

Too bad videos don't weigh very much anymore; I say at least 20x it's weight in gold!

Good stuff Ralph keep up the good work, and thanks for the formula sheet I'll put it to good use.

You are welcome! I am glad that the formula sheet will help. I made a copy and put it in my lab notebook myself for future reference. 🙂

The bias circuit is the worst type of bias. With temperature changes the collector voltage will be very unstable. The best type of bias is using to resistors in the base of the transistor, which adds complications to the design.

Absolutely, totally correct!😀 This was the most basic example of a common-emitter circuit. It is intended as a *primer* on how to go about the analysis and design of transistor circuits. As I said in the video, this is fixed with the "beta-stabilized" version. The addition of an emitter resistor and a voltage divider bias. As I also said in my video, there is a video coming in which I work through this whole design. In fact, I am in the midst of creating this video, even as I type. So, stay tuned ... the best is yet to come. 🙂

Effect of measuring device (not just transistor circuits) --- why we used to use VTVMs rather than VOMs while measuring ...

WHY DID YOU USE 200 FOR BETA AND,NOT NOT 100?WHEN I DID THESE CIRCIUTS IN THE LAB IN COLLEGE WE TOOK A SOLDERING AND,TOUCHED THE TRANSISTOR WITH THE TIP AND,WATCHED THE CURRENT INCREASE IN THE BASE AND,COLLECTOR AS IT WENT INTO THERMO RUN AWAY.

The datasheet I have here tells me that the hFE can range from 100 to 300, so I picked the value in the middle. Admittedly, the wiser choice would have been 100 for the sake of thermal considerations. 🙂
