What Is a Diode?

This electronics video tutorial provides a basic introduction into diodes. It explains how a diode works and how to perform calculations when it's in series with a resistor.

How To Solve Diode Circuit Problems:

Diode Logic Gates - OR, NOR, AND, & NAND:

Clipper Circuits:

Bro little you know you are raising kids because of your passion in teaching. I started watching you since highschool learning algebra, now I'm college studying computer engineering. You've taught me calculus, circuits, physics etc. I've learned so much from you, thankyou.

now i graduated, proud cumlaude🥰

[kozimambo]

i really dont understand how you can be so good in every subject, i mean this is too much yet you can still explain so well

[awinimaxwell]

You always make me feel like the things we learn are not difficult just that those who are teaching us are not passionate. Thank you very much.

[zEre]

My lecture was 2 hours and a half, and you explained this in 12 minutes, wow!

[jeshnu]

This guy is a life saver for many students especially test before a
notice this is guy never said to like share or subscribe hats off dude

[katiebell]

I am wired for just physics and mathematics, this instructor seems to be wired for every course imaginable. And he is good at all of them. Does anyone else imagine him to be a tall, lanky person with long hair.

Can i say how much i love ur voice? Its sooo soothiiinnggg

[ilsemiller]

I’ve recommended you to all my colleagues. Keep up the good work.

I remember which end is the anode because the arrowhead in the symbol for a diode looks like an "A" (for Anode) on its side. It points in the direction of "conventional" positive-to-negative (P-to-N) current flow, which reminds me that the anode has P-type semiconductor, and the cathode has N-type semiconductor. The vertical line for the cathode represents a wall that blocks "conventional" current from going from cathode to anode. That "wall" is represented by a ring marked around the cathode end of a "physical" diode.

bet one day you'll get interviewed by TEDx wanna see face reveal lol, keep it up I'm almost reaching 3rd year ECE btw

[parkmejihyo]

Sir you tought me more in 12 min than my professor did in the entire college semester

[TiberiusStorm]

I could've used this video about 2 months ago for my electronics test!

[vrisfaster]

Thank you so much for immediately differentiating conventional current vs actual electron flow in your demonstration. The difference here has confused me when reading schematics ever since I was a young student-age child.

[eggxecution]

hey you reach 2 million subs now, I'm very proud keep it going mate!

[hasanrants]

tomorrow is my applied physics exam, thanks alot man! you really made diodes easy to me.

[Mylovelycatworld]

this channel is so amazing, you make a lot of things easier for me. And your voice is amazing, It is like some ASMR.

[crystalcoke]

Without you I do not know where I would be tbh you're the best

[devanshusahu]

damn .. that video was so crisp, clear and perfect.. learnt the concept i was struggling for so much time!!

[levernis]

You are really the GOAT at teaching. Ty for this video.

Another great lecture about diodes. I like the examples at the end. My only wish is that he elaborate on what it means to be a n-type or p-type in physical terms.
