7 awesome applications of transistors in circuits

You can't imagine what transistors can do for you. After learning to use transistors, your ability to design sophisticated and advanced circuits will improve.
I know most of the newbies think about using transistors in their designs, but they are confused where to use a transistor!
In this video, I am going to tell you about seven applications of transistors in circuits. This will be a good time for you to start using transistors.

In this video, I am going to answer this basic question, "Where to use transistors in circuits?" along with a lot of other questions about transistors.

The main problem I have noticed why people don't know how to use transistors, is the teachers. They are starting electronics with transistors, and immediately dive into the deep end of transistor analysis and different types of transistors, without actually ever explaining what they are and what they are used for. Even on the first introduction to electronics, teachers start throwing around words like FETs, BTJs, IGBTs, NPN, PNP, emitter, controller, base etc. never actually telling students what those acronyms mean.

For example, a few years ago, I participated in 1st year students electronics course in an University as an undercover student to troubleshoot why everyone was failing these lessons. I have a few engineering degrees and although my electronics degree is from the the early 2000s, I could barely follow the class and had to correct the teacher several times on critical (possibly fatal) theoretical errors, because he thought they were so obvious everyone would know that he was talking about only a very limited use case with a lot of safety precautions in place. With the excuse that I had "just read on a the internet that isn't it like this instead?", since I couldn't just let those things pass. Then the after the 2nd week, theory was over, and we moved to lab to start building a full audio-amplifier. Basically, everyone just followed instructions, but didn't understand anything they were doing, and learned even less. I won't name the school, state or country

The teacher was a former electronics virtuoso from a top name company (that still did consulting for them, but had downshifted to teaching), but he was so disconnected from beginners, he was talking and teaching to them as they were all post-graduate students, and just excepted everyone to be at that level coming in to the first electronics lesson. Also, for some messed up reason, physics I and II were scheduled AFTER the electronics courses.

Many many thanks for explaining how easy it is to use these little devils. I have lots of transistors, but never use them and stick to simple circuits for fun, but now that you have explained them to me, I will start to use them in my circuits and get all the benefits that they bring as well as enjoying electronics more.
Thank you so much,
Joe

Ahhh, this is outstanding stuff for the audience you intended this for & I most definitely count myself as part of it! I'm in the "Super eager-to-learn electronics enthusiast w/zero formal schooling & 100% self-taught" & transistors are like the Next Big Step for me that I've procrastinated LIKE CRAZY on implementing in any of my projects all just bc of how intimidatingly arcane it was for me to try & learn even the basics about them w/o any primer. Pretty much any "intro" to transistors & semiconductors in general might as well be written in sanskrit if you don't have a grasp on the lexicon going in, so thank you for the effort to help bridge the gap for people like me!

Another excellent review deepening my understanding. I'm an Amateur Radio operator and electronics hobbyist since childhood. This is an area that I clearly grasp but still was not fully confident. Logic was easy, but other applications are now much more clear. My Sansui QRX 7400a is clearly an example of class A B amplifying. But PWM and other applications I was not quite clear on. Your examples are very helpful, thanks again..

[armonfrohlich]

Exactly what I'm looking for. Not just the bare explanation of how a transistor works, but even several examples what they are doing and above all why that's important.

Cause, I never understand realy why I should use a transistor as a switch after e.g. an push button.

Direktly saved in my learning list!

Thanks

Excellent Explanation . you taught me so many things in just 27 mins which my college failed to teach in four years. please keep making the videos which is very helpful for knowledge seekers like me. Thank you so much

[acestudioscouk-Ace-GACE]

Showing the practical applications really helps, thank-you!

[Sameer]

I refreshed my memories especially about Switching, for me, transistors will always be switches though 😂 thank you so much for this video

[mustafaiqbal]

No word of a lie, but I'm in absolute awe of your encyclopedic knowledge of electronics. Wow!

In a simple and short words "you are just amazing man"

[tameezdevos]

Thank you sir, now I know how touch buttons on certain old elevators work on the inside ! I’m a lift mechanic and nobody could explain it to me on a component level!

[amazagx]

Your approach to teaching is unique, practica, clear and previous!!

It’s seems all so natural and easy to explain these topics your way!! But it’s clear that there is a lot of preparation An planning before each video.

Thank you very much!!

I just discovered you today but U will come back often!

Salam dorud. I suspect you're Iranian. That makes you the second great Iranian electronics teacher I've found on YT. You're tutorials and contents are fantastic and you're channel will grow fast. I'm from Tehran.

I discovered you few hours ago. I subscribed after first 5 minutes. Thank you for your work. Your content is so good. Greetings from Romania.

[kennymanchester]

Absolutely outstanding presentation which leaves more room for more. Particularly interested in RF amplification applications and also discussions about filtering in all types of amplification using transistors. Terrific presentation as usual. Many thanks. 73, NZ5i

Just subscribed your channel for your beautiful explanation with practical knowledge. Keep it up. Lots of love from INDIA..

[gazzacroy]

this is one of the best videos i've seen about transistors. i found this so helpful thank you :)

[msxcytb]

Excellent content with good examples! Thank you!

[antonio]

Man, this is a very comprehensive video with very interesting applications. Thank you so much!
