Something good to remember 0.7 v is the minimum voltage required to turn on a transistor

0:41 Note: _solid state_ here means with _no moving parts,_ that is, no human intervention is needed to toogle the switch (the transistor.)

Watched 3 videos on why transistors were so important and how they worked and didn't come away with anything useful. Watched two minutes of this video and understood exactly.

Nice explanation. Im glad someone is actually putting things into laymans terms. Thats basically the same way i learned about transistors, Except in my case i learned it was basically a miniturised version of a relay used in general automotive applications.

2:50 I’ve watched so many videos and never understood transistors, and these 30 seconds explained it to me better than anyone else ever could (I’ve worded this comment funny, haven’t I?)

Thank God. An easy Explanation !! Much Thanks.

this is the best explanation of transistors I've seen on KZfaq.

Loving your channel man. These videos are excellent. Also, you have a really good voice. Extremely clear and articulate

A Good and simple explanation of how a switching Transistor works. Thank you

I am an absolute amateur with electronics, but this video his on the head a little side project I'm working on: controlling an LED strip with a microcontroller using PWM, something I was kind of considering necessary but not sure how to do. This makes it way more clear. Great video!!

This was such a to the point, concise, easy to follow and easy to understand explanation!! Thank you!

These tutorials are very helpful. I will review and repeat reviewing until I absorb the information. I am grateful and I thank you.

Finally some good explanation how transistors work!

This is probably the best explanation I've seen so far. Thank you!

Really enjoyed all these videos, more please!

Best explanation of a transistors I have ever heard . Thank you.

I have watched up to 10 videos to unserstand transistor and this is the only one that solved my problem. Bravo mon ami . vous etes formidable.

Oh mahhhh gaasssshhh💥💥❤❤❤❤❤❤❤❤❤❤❤i love youu so much!!!!! Have my physics exam tomorrow and I've studied and have understood all concepts in the syllabus except electronics MAINLY TRANSISTORS. Now I've finally understood through this explanation!.....YOU ARE A LEGEND!!!!❤❤❤❤

Very well explained.... Keep up the good work... Spread knowledge.

This is the best explanation I have ever seen about transistors

Hopefully I can pass my 400 level advanced circuits final next week at MIT since I watched this video now, wish me luck

The circuit animations are fantastic.

Brilliant, if only it was explained like this for me in college!!!

Nice clean explanations. Subscribed.

thanks !

I don't know if you're still reading comments to your videos, but your videos are excellent and easy to follow for people new to electronics.

thanks for this video...simply taught and catchy too!!!

Great content !!! I've subscribed

I like how you explain things. Thank you

You make it look too easy. Great stuff bro u r awesome!

simply great tutorial, thanks.

Watched two minutes of this video and understood perfectly!

You are awesome... I wish I discovered your videos since

Didn't understand transistors until this video. Thank you!

I didn't have facility during my college days.Thanks for easily understanding video's.

Very educational!!! Thank You

thank u so much....best teacher alive

thank you , nicely explained !

Comment 345 A good teacher is one who makes a complicated and difficult concept simple for the student. Obviously you are one, Best Wishes from Singapore.

Great video! I love the way you explain things so everyone can understand and enjoy electronics, tho if we have transistors why use relays?

I hope i could find these videos when I was doing my engineering degree 15 years ago. Then, I won't end up hating this subjects after all these years. Just there were no one could explain to me how a transistor works and that made me losing the interest on the subject.

Clearly explained. Thanks

Really good easy to follow explanation, I tried wikipedia first, but as usual it was rather opaque.

What software do you use to simulate your circuits? I love the way you use it! It makes it easy to visualize what is happening at the atomic level.

Amazing video, thank you

Thansk , much appreciated its simple and very easy to understand

Its a great and cool explanation 🙂

Very good illustration of transistors

very educative thank you regards,

This helped a lot thanks

GREAT VIDEO!

Enjoyed the video.

These are great tutorials.

Very good.thank you for the information..

Solid state switches, who knew. Great explanation!

Sir hearty thanks for this channel. please keep more videos related to electronics.

awesome tutorial

this series taught me more than what half a semester of 3 hour classes could teach me.

something that has caused me so much grief, now in 10 minutes, voila! Thx

SOOOOOO Helpful.

Very well explained

I finally get it. Sounds like the same operation of an old school control relay activated by applying voltage to the coil thus operating the relay contacts into the desired state to either pass or restrict current flow.

Where do I find the Symbol to utilize Logic Level Voltage to the circuit? I love your videos, but I'm stuck on this one. Help! Thanks!

What a fantastic little invention.

From 2:00 even the simulation shows no current from Collector to Emitter and nor should there be. The LED is just in series between the two cells. Circuit at 2:35 fixes this.

which tts speech synthesizer did you use to make this?

Good work...!!

This is very clear and high skilled explanation. You can’t find in most of the higher education colleges. Thanks sir, but I have a question about voltage level being applied directly to base of a transistor without voltage divider. I thought only a voltage of about 0.7 volts can be applied directly to base. Now in the above circuit we have 3.3V, is that level to high and can damage the transistor junction?

It's a bit unfortunate you did not clarify that this example is using a BJT, which is an analog current-controlled device, NOT digital voltage controlled as you implied in the video. It seems you were explaining the usefulness and operation of a JFET but using a BJT in the example. It would have been nice to touch on the differences between them since transistors range in their operation and are not all alike. I usually use Falstad for circuit simulation, so I'm guessing perhaps EveryCircuit doesn't have the same options, but it would've been nice to at least make that clarification in the video.

thank you for your episode 22, it very clear to understand. can you tell us which component used for on and off the LED and the link episode used. many thanks.

Neat! Cool video!

The first diagram shows current flowing out of the transistor collector back to the 3.3v power supply and out of the emitter to the 3v power supply but in the video it says that the current goes from the led through the transistor back to the 3v power supply. I thought when the transistor is turned on that current only goes one way through it? The way it’s drawn out in the second diagram makes sense to me but the first one has me confused...can anyone help me understand a little more please?

Excellent !

Very very very helpful

Sir what is the transistor number that you used in the circuit?

Transistors and chips are relevant for making switch-possibilities in a computer. Thanks for the explanation

Superb Video 😍

Really like what you are able to show your audience. But it should be mentioned that current flow is from negative to positive.

I love it!

Great video I just liked and subscribed. Question I have is within the video and working diagram at about a 1:45 min mark, the diagram is showing the current flowing away from the collector. Is this how the top 3.3V circuit is completed? I am not following/understanding the visual motion here. I would have thought that the current would go into the collector and then out through the emitter. Is this not the case? It also seems odd that the direction the simulation emulates the current , I was always taught that, contrary to what you would think, current/electrons travel from Negative to Positive.

Where did you get the digitally controlled voltage source? I don't see it on the premium toolbar.

Thanks man.

Very very good and nice video!!!😚😚😚😚😚

Sir please reply how the current flow in the circuit determined.Couldnt understand please help..

One thing confusing for me is that some of these videos show the electron flow and some show conventional flow for demonstrating the direction of the current in the circuit. It seems this video is backwards, it shows current moving from positive to negative, when in reality the electrons move from negative to positive, which can be observed in other videos from this channel. Its making it a bit harder to conceptualize trying to reverse it in my head.

In 5 minutes you taught me 5 years of schooling. Thank you I subscribed

Thank you!

How can a small 3.3v supply a 12v? It just can? Or it could turn on the path to the higher voltage because the 0.7 is psssed? Or there's no explanation?(mostly in our school there's no explanation as to why these components work)

You are the man

Man, you are good

Hi! Please, could you tell us which transistor should be installed to use only 01 battery increasing 1.5V to 5V to work an active buzzer 5Volts? Good video - easy to understand. Tnx :)

Thank you

Thanks a lot for the informative video. What is the name of the computer program you are using to demonstrate the circuit?

Why is rhe bade sometimes calked gate, is this yet another example of uk vs us englusg or is it just ibconsistant naming for other reasond

This may indeed help me with a problem. I have a couple of transistors on a board that I am trying to repair all with a random wire pulled away from it resoldering it would be annoying and a shot in the dark if I had no clue how a transistor worked.

Perfect 👍

intelligent teacher

It is so interesting

I'm trying to figure out a circuit that turns on a motor when the light input to one LDR is greater than that to another. And turns off the motor when the light input to each is the same and turns on the motor in reverse when it is the second LDR receiving the most light. If I can make two of these circuits I can design a device that angles a solar panel towards the sun. I saw a crude solar tracker someone made using small solar driven motors that simply fought one another, the motor receiving the most light to its panel winning the tug of war, until both motors stalled out when the device was pointed at the sun. I was curious to design one using transistors though.

Cant we use a one power source to power both transistor and LED. ? Use one wire with a resistor to power transistor and one wire to power led or motor?
