Thanks for the video Rick. I've been servicing equipment for a long time, and in recent years started repairing valve guitar amps - something that I really enjoy. There's always something new to learn and I certainly gain a bit more knowledge every time I watch one of your videos. All the best and I hope you are well!
Hello Rick, Good to see you as It were. Glad that you are doing well. Thank you for teaching me electronics and being a long time loyal sub, I really appreciate all you do providing quality, credible information. Been with you about 10 years now. All the Best from Oregon, Cass.
Thanks very much Cass, I very much appreciate your comment. I hope my videos have helped you understand concepts so that your studies are more meaningful. Thanks again, Rick.
This is not only a good demonstration of transistor amplification in general, but also a very good visual of how a bipolar transistor is a current amplification device, rather than voltage amplification as a Field Effect Transistor would be. Might be a interesting follow-up to do a similar circuit, but using a FET and compare the differences between the two. Regardless, a great tutorial as always.👍
Hi Rick, I did your experiment several times. As I measure e-b voltage .06v, I turn the pot the reading goes to -.660V which is causing the transistor to go into forward bias for an instant. The led flickers and then is off (V) is also zero then as I keep turning the voltage comes back to -.660V the LED is on again. I'm not sure what I'm doing wrong, hehe my values are very similar to yours. Enjoying the video and your teaching. 👌

Hi rick, i watched a video of yours from 12 years ago about push pull amplifiers, and i cant wrap my head around the part when the normal and inverted signal combine. Because one is negative, and the other one is positive, shouldnt they interfere and cancel out? Thank you in advance.
Mr. Rick I have an old 1971 single channel transmitter and receiver that's in an old model plane. I would like to see if you could explain to me ( electrical) how this simple radio works. I love your videos and have learned so much. I could see pictures or a video of the unit. Thanks Clay
That would be interesting. Right now I do not have any type of remote controls for an model airplane or model cars. I will keep this idea in mind. Thank you.
I have been thinking about this and I would need the wiring diagram of both the transmitter and receiver. The manufacturer and model number would also be helpful. You can contact me at allamericanfiveradio@yahoo.com make the subject remote-control transmitter receiver.
Thanks Carl I had thought about how to show base current and collector current visually. Not just using meters readings. I thought about this for a week or so, and tried several ideas. Putting the same LED in both the base and collector I thought might work. Also I don't believe I have seen that done anywhere. And it worked, I think it makes a good visual demonstration.
He's demonstrating a tiny current on the base thats not enough to light the LED on the left but is 'amplified' to provide enough current to light the second LED, the term "Amplification" does not just apply to audio. This demo explains perfectly whats going on so I suggest that you watch it all and you will see how it works.

You hit it out of the park once again Rick.

Thanks. I'll look form may FETs.

@@AllAmericanFiveRadio Thanks a lot!!
Another great video, thank you. I like how you highlight things and then explain what's happening in the circuit at that point
Thank you, and your welcome.
Nice demonstration showing transistor current amplification from base current in uA to collector current in mA.
Thanks.
A novel way of demonstrating the relationship between a voltage divider and the current that commands. Eye opener actually.
You learn mostly with your eyes. I wanted a visual demonstration.

I have several videos on this subject. This video may help.

As usual Rick another good video and very well explained. Thank you.
Thank you, and your welcome.
I love the 2N2222 and I see you have the metal can package, I wish I could get them but all I find are to TO92 plastic ones...cheers.
Thanks.
Can you do an explanation of the transitory circuit modes (common emitter, base , collector) with some basic math?
I have put this on the list. Thanks.
Excellent way to show amplifying in a circuit. I can see the FETs coming next Rick.... ;p)
Thanks Carl

I always learn from your explanations! Thanks Rick!
Thank you, and your welcome.
I love these kinds of videos. Thanks for posting!
Thanks.

Amazing! Thank you my friend.
Thanks.
Oop,s I forgot ! great tutorial !...cheers.
Thanks, and your welcome.
What are you amplifying. ? I see two red led. I see no audio source.
