This dude is such a fucking legend. Saved my ass freshman year and helped me pass chemistry after I had a D at thanksgiving break. Haven’t learned much in my electronics class that I took a year ago and I’m so lost in electronics 2 now and here he is saving me again. This man is a genius and has a gift for teaching others 🙌🏻
15 years ago a Darlington transistor pair popped up on the 10th question of my 80 question Master Electrician exam. I was like...”What is this sorcery?”. I had no clue what I was looking at. The prep course for that exam didn’t go too far with electronics, diodes etc. Transistors, explained by this tutor, were the perfect gateway for me to go beyond timer relays and basic sensor knowledge.
You are literally the reason i have passed school. I never understand my professors due to there heavy accents and they always teach way too fast and too much at one time. Somehow you always have a video that explains in depth exactly what i'm learning. You deserve an award, thank you very much brother
This guy really does lay things out well. Helps me to remember the emitter arrow always points to the negative and the base is connected to the positive if it's a P or to the negative if it's an N. I need all the hints i can get to help me remember which way things go.
Great content!! Wish you were my lecturer during my electronic 101 basics back in the days. In one video I learned more than I grasp in a semester. It will be well with you Sir..
Truly speaking you are the best lecture I have ever seen my entire life, you have changed my attitude towards electrical electronics knowledge, thanks keep up the good work.
I've listened too literally almost every tutorial on transistors but you explain everything in a way my brain can comprehend it PLEASE appreciate what seeds have planted w/me and others and I sincerely pray you get to see the fruit you alone have grown in this lifetime
This guy helped me with my o levels, a levels, first year engineering and maths and now with second year engineering and mathematics. Idt there's any other channel that could even compete with this
ngl, this is the best educational channel, i literally found everything that i had a problem with, most teachers didn't make it to teach us this way, and u simply did it, Thank you so much
WHAT A PRESENTATION. I appreciate you a lot for the content of this video. I legitimately thought I had no hope of understanding the nature of transistors until I gave this video a try. Thank You 100x for the great electronic explanations.
Whenever I feel like dropping out, I find your videos and fall in love with electrical engineering again :) you saved my life in high school and now in uni. Thank you so much
Holy shit i love you so much. I have just started electronics course, and we are having transistors atm. Since the lectures are garbage you are helping me out a ton! Please more content related to transistors / OpAmps / Oscillators

Voltage drop across LED is approximately 2V 23:50 3 operating regions of transistor 27:38 the importance of Vce to determine which operating region it is
Who the heck is Julio Gonzales! His videos about electronics are immensely miraculous! (I am sure other subjects he speaks about are equally excellent. I focus on electronics at present)
Very useful. Easy to understand. Well explained. Be careful not to confuse BPJT npn, with MOSFET N channel. In an N channel enhancement MOSFET, the gate(base) voltage has to be above the drain (collector) voltage, at least by the gate treshold voltage. in a MOSFET the gate(base) is completely isolated/different circuit to the drain-source. BPJTs are obsolete. MOSFETs have superior technical performance.
Gerat video. I'd like to comment on the saturation region of operation mentioned at 16:54 and 28:29. Rc must be large enough and Vc must be low enough so that Vb > Vc, and the base - collector PN junction for this NPN transistor becomes foward biased. So, in my mind, saturation is not just any old Vcc / Rc or just the max current of the circuit. It's Vcc / Rc if (and only if) Vb > Vc. In other words, the base-collector junction must be forward biased to have the transistor operate in the saturation region.
Thank you for this video! Super helpful for visual learners. The textbook for this course just gives me headaches LOL these videos on the other hand...
Your series are the best! Always have been a software developer, but for the past 1/2 year I got interested in electronics and even developed my own LiPo UPS for example thanks to your great tutorials. Keep up the good work bro
Great video. I’ve seen many videos from many teachers but one thing or another is always missing in the intuition. So I learn something different with each video. Had no idea transistors act like diodes connected to each other.
You have great teaching skills,just a small tip,when drawing a transistor symbol don't connect C and E,it is wrong to do so cuz it looks like C and E are connected directly. Keep up!
I agree with most everything he says except the way current flows. It was instructed to me that current flows from negative to positive in a DC circuit.
That is the flow of electrons, since they hsve a negative charge, they flow from the negative to the positive. When talking about current, it is conventioned that the flow is from the positive to the negative sides. Most formulas and rules apply to the current flowing the way its conventioned, so I suggest sticking to it when doing your own calculations to avoid unecessary mistakes.
@@RBgamesbr Agreed! Most electronics technicians and design engineers pass their entire working lives using conventional flow and it doesn't make a blind bit of difference. As a physicist, I only need electron flow when dealing with electrochemistry, magnetic fields or gas discharge tubes, x-ray tubes, thermionic valves etc., otherwise conventional flow is just fine for circuit diagrams and totally irrelevant for AC circuits.
Really admire your presentation;however, when Q1 Base is high enough to essentially close the Collector Emitter channel, or close the switch, the Vce or potential between the Collector & Emitter is effectively 0 Volts (or .6V) not 7.49V as presented. Vce would be 7.49V in an inactive transistor state (or open switch if you will). Thank You Again!
Are you referring to the section around 23.03? Should he have called 7.49V Vc rather than Vce? Or is that the same and should be .6V? Thanks trying to make sense of this
That is incorrect i think. Since the Transistor is operating in forward active mode, V_CE is actively blocking some current from flowing through it. This results in a potential difference btween C and E. The 7.49 Volts are correct.

BJTs aren't obsolete. You can use them for current amplification. You can't do that with MOSFETs because they are voltage-controlled
Really high density information explained lucidly in such a small amount of time !
I am majoring EEE rn and I am positively surprised that you have videos about transistors too
thank you so much, these videos are what help me pass my classes.
This is the best transistor video available online ....thanks so much for this...God bless😍😍😍

clear as the day as always keep it up and many thanks
Thank you very much! Very informative as always! 😊
Thanks your videos really helping me out continue making great videos
I have a question at 12:58 , why is Vc = 9V, I thought there will be a voltage drop at the resistor Rc, so Vc should be less?
This guy legit know everything..
