- เผยแพร่เมื่อ 17 ต.ค. 2018
- Today, we'll explore the materials electrical engineers work with. We'll look at high-conductors, insulators, and how low-conductivity conductors can be used to generate light and heat.
Crash Course Engineering is produced in association with PBS Digital Studios: • All PBS Digital Studio...

I could listen to this woman talk all day.
ElectroBOOM!!!!
FULL BRIDGE REKTIFIER!!!!
1:20 Wow, that visualization is so good it should be used in schools
Thank you for this. This it more than perfect timing.
My girlfriend is taking an introduction to electronics course, this is exactly where she is right now, and she’s been having a very hard time visualizing the concepts.
I love that there was a Kodama figure on the shelf in the house
5:26 electroboom Easter egg
Intro electroBOOM as well.
The swedish name for tungsten is wolfram. So i'm confused.
5:26 FULL BRIDGE RECTIFIER
ElectroBOOM makes a guest appearance on TV at 5:30! And Picard Borg appearing at 6:50. Awesome :)
06:49 "resistance is futile..."
oh! A borg ;)
.
.
nice Star Trek reference.
I just love everything about this channel... the quality is on point..
Electroboom on the TV!
5:28 ELECTROBOOM ROCKS
Love this series!
The animation is just right.
"Semiconductors are somewhere in between conductors and insulators"
Oversimplification of the century.
How about "Semiconductors are a shitload of conductors and insulators"?
This episode isn't about them, so that's the point. We don't need to know about them right now.
Im truly grateful & blessed
Thanks Crash Course!
thank you helped me soo much
I love the animations.
any ideas what software they use for that?
Adobe Illustrator and After Effects
Look it's "ElectroBoom" 0:04
Love electrobooms channel!
ELECTROBOOM WAS ON THE ONE TV, I HECKING LOVE YOU GUYS
You guys are helping to save the life of this English student who has to take a material science GE course >
Hearing Americans force a British person to pronounce Aluminium as "Aluminum" is just so so wrong
I know it was just jarring and wrong
It was consensual.
Interesting how she got Solder right but mispronounced Aluminium. But then again they've even started to spell it wrong.
@@Hansca I've never heard the L in solder.
Interesting what you get used to. Americans and some Canadians are the only people I've heard drop the L in solder. It was harsh of me to say that it was wrong to say Aluminum as language is an evolving thing and who am I to say what's right or wrong but it does jolt my brain every time I hear Aluminum and soder.
Interesting video
1:27, "Charge is flowing in the opposite direction to the electrons", do you mean positive charge?

LEDs are certainly more efficient, but they're only better for the environment if you're using coal rather than a dam to get your power.
Interesting. Why though?
@@heyoladies7118 The manufacturing processes for semiconductors tend to produce more toxic waste than extracting the raw metals needed for incandescent bulbs. Seeing as hydroelectricity done right has only a localized and minor effect on the environment, the claim that LEDs being more efficient makes them intrinsically better for the environment is a bit simplistic. There are more dimensions to the problem than that.
The proof that there will never be time travel:
A) The person who invents the first time machine will be an engineer.
B) An engineer with access to a time machine would immediately go back in time and slap Benjamin Franklin in the face until he guesses the charge sign of electrons correctly.
C) Benjamin Franklin did not guess the charge sign of electrons correctly.
B2) Ergo no engineer went back and slapped him.
A2) Ergo no engineer ever has access to a time machine
D) Ergo no first time machine is ever invented.
Can't believe the script writers made Shini say aluminum. I know both pronunciations are valid in modern dictionaries but even Hank made a point of highlighting how aluminium is the correct form.
More more more materials 🙆
will graphite/ graphene/ Carbon be in the next video?
I didn't know copper was rare, it was the most common ore in minecraft mods :P
HERE!
"Inverse Ohms" sounds so tedius. I hereby decree that the term "nOhms" will now be the standard term for 1/Ω
I wonder how electroboom would explain this topic?
he already did...
Haha I just went over this two weeks ago!
You can work and research electrical power, conductors etc following the career of Electrical or Mechanical Engineering.
What about audio equipment?
What about super conductors?
Some body know about Magnus effect?
Why don't you make crash course Mathematics?
Because maths takes a lot of preperation since it is so big and branched, they have crash course statistics which is a branch of maths.
@@habeebhabib3160 Why don't they make something like crash course geometry?
geometry is also a pretty wide branch of maths, however, they can do that and they should. so I do not know why it is taking them so long.
do you need help with geometry??
It's more likely that they will make CC's about smaller branches of maths. Like they do right now about statistics
We always called the inverse ohms "mhos". Is that not the standard?
James Pace Electronic types use "mhos", but physicists prefer "siemens".
Mhos went out like...50 years ago!
mhos still used for distance protection in electrical systems.
So what is on the agenda for the next episode?
I sing of power electric
Copper mines are made not found as cell phones or power lines.
Electroboom in the tv
Wolfram?
Wheres hank
FUUUUUUUL BRIDGE RECTIFIER!!!
We are in the midst of an unrestricted ennobling of energy that will clear a path toward the quantum infinite itself :-)
JEOGRAPHY I don't even understand what you said.
It means I'm going to fart so hard my intestines will be unloosened.
please in spanish
What’s next?
ELECTRONics uses positive current flow, oh the irony, the rage inducing irony.
Maybe semiconductors?
Brian Miller
The animation at 1:20 actually describes how holes move in a semiconductor. As you can see no positively charged particle actually moves, since they're locked in a crystal structure. Even though the formal positive charge moves the electrons do all the work.
The places where you've actually got positively charged particles moving are the electrolytes in batteries and electrolysis cells and in particle accelerators. Maybe also some other places I can't think of right now.
mwalsher
I know the convention predates the discovery of the electron but it still ticks me off. Positive current flow is easier for electronics (because of said convention), electron flow makes more sense for electrochemical reactions and the physics behind electronics. Though I've heard old timer electronics guys confusing the two and saying electrons in a vacuum tube flow from anode to cathode....
Things should have been set straight immediately, sadly it's too late to change the convention now.
There has been a 50/50 chance to name the poles right and they missed it. If they did it right, electrons would be positive and the flow would be right.
Oxygen Not Included
Wait, Brits pronounce the "L" in "solder"?
HIII HANKKK
Life is a manifestation of logic.
Logic needs a language.
Knowledge requires a teacher.
Hence make a crash course on Mathematics.
Wow she is shocking
I'm the 8th comment, cool!
Let’s be real it was mostly Tesla
Copper is not easy to weld lol
(very focused and typing with one hand)
I'm ok with Americans say Uloominum. Don't be a British and say that. It's bad.
This is awesome, but you have to wonder how all these high powers lines are effecting those who live in close proximity to them...
No effect whatsoever
Moses Emmet Considering that electric power has been in use for about 130 years, no effect at all.
@@TheChipmunk2008 there are studies that show otherwise, look em up
@@davidlugarov9685 I have the only few that do exist are only a correlation and not a causation. The human body does not respond to low frequency electromagnetic radiation.
@@TheChipmunk2008 thats not true, multiple studies show that all kinds of electromagnetic exposure can harm us, even the us navy has an entire study on low frequency em radiation
Can you be my teacher?
she's really hot
Great video and all, but…
Use original names for elements, please. This rips my ears. It's wolframium, not that…eeeeh-word. Why it's wolframium? Check periodic table. Element 74. What do you see? W. And W stands for…? It's really not that difficult.
And the same for aluminium. Not that americanizet butchered version. Then cuprum, argentum, etc.
And it's röntgen. Not some mysterious X-rays, when nobody really knew. We know now. Thanks to whom? Röntgen. Again. Simple.
