Hopefully I can pass my 400 level advanced circuits final next week at MIT since I watched this video now, wish me luck
What software did you use in the video

current flows from negative terminal to positive…
In 5 minutes you taught me 5 years of schooling. Thank you I subscribed
Sir please reply how the current flow in the circuit determined.Couldnt understand please help..
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.
You are awesome… I wish I discovered your videos since
in some video it is shown current flows from negetive to positive and in some from positive to negative plz clear in which direction its flow
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.
How much current can a transistor handle? also are they replacing relays?
I thought that symbol was a new gender, until I checked out the video…
You forgot to include a current-limiting resistor at the base; in a real-life circuit, instead of the current simulation, without it, the transistor would fry the moment the voltage-source at the base is switch-on.
this series taught me more than what half a semester of 3 hour classes could teach me.
This is probably the best explanation I’ve seen so far. Thank you!
👍
thank you it clicked
Is it possible to switch a transistor on and off at a constant rate just by using DC power source and that is, without using any microcontrollers..??
Must the voltage going to the base be pulsating? What if we use a small battery?
Thank God. An easy Explanation !! Much Thanks.
How come in other’s video, the power from the battery flow from the negative side?
I wanted to know more episodes of different types of transistors for better understanding.
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.
Need a circuit solution? Why not use this Look for: ‘Circuit Solver’ by Phasor Systems on Google Play.
Good
Why does the current not flow to ground? What keeps it ‘in the circuit,’ and not go to ground? Path of least resistance?
I love it!
Now explain to me how a vacuum tube works using hole curret flow???
i find a way to self power without out side power option . 20 days take me to find the way omg what mind boggling
Reading through the comments I’m amazed at how many are of the form "I’ve studied electronics / transistors / circuits for weeks / months / years and I never understood them before this video."
Congrats on a helpful video, but seriously folks, people were learning about transistors from BOOKS for decades before YouTube was invented. I have to wonder how some of you manage to function in society. The basic concept of a transistor a little more than a voltage or current controlled switch.
If that concept was difficult to understand from pictures and text, you have to wonder about reading comprehension skills. I’m sorry if that sounds insulting but, it sounds like there are a lot of people that could use some help with reading.
Very well explained…. Keep up the good work… Spread knowledge.
why does this video have current flowing from positive to negative?
very nice for me is more common sans where we use and for what
0:41 Note: _solid state_ here means with _no moving parts,_ that is, no human intervention is needed to toogle the switch (the transistor.)
How does it work as a high speed switch….pls reply
Good work…!!
Neat! Cool video!
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.
What is the name of this software you use?
Is the base always the middle tap
I wish you would teach accurately, electrons flow from negative to positive in the real world.
Great vedio
awesome tutorial
Very educational!!! Thank You
This is DC right? Does it work in AC?
You should use electronic current instead of conventional current
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.
I didn’t have facility during my college days.Thanks for easily understanding video’s.
This is not correct at all! First current does not flow at all, it is simply present! Electrons flow and they do not flow in the direction which he told us! Electrons flow from negative to positive and not positive to negative! He needs to get his facts straight before he attempts to teach!
Doesen’t voltage (electrons) travel from negative to positive the opposite shown on the circuit?
