Incredible video! Clear. Factual. Useful. Allows you to instantly apply concepts on your work bench. So much CRAPPY university prof material out today to wade through...
these videos were made when America was at its best. Videos like this will never be made again.
Sounds like he is from Houston, TX .....then did some speech training.... Glad I did my electronics tech training in the Military, USMC first before going to college for engineering, this gave me the solid fundamentals... Most of the professors at University suck at teaching....they do not start out with any conceptual teaching....They jump into Maxwell's equations on the first day..Many students drop along the way...It's not until after you graduate that you have time to think things through....

plus i've heard that the Maxwell's equations are not allways working.

greetings from egypt to united states , thank u the dep. of defense very much . its a great effort . science and technology nowadays becomes the greatest weapon in our world .
That is a great video. I really like the Tech Sergeants cowboy voice! I remember going through BEE-Basic Electricity and Electronics in Great Lakes before A-School and they had all kinds of videos like this.
Thank You, Father God ✝️
In every school there shoud be a major like this one (I am not sure about his grade - I am from Europe:) ) who explains everything so clearly and his voice makes the public listening !
Wow, these old videos are throwback!
Transformers! Robots in disguise!
i learn a lot from this video.thanx for uploading B tech Electrical salahuddin form sarhad university
More than meets the eye!
I have been working on this stuff for years, taken classes and read books and these videos are some of the best things I have come across. I wish I just watched these first and save myself tons of time. It's crazy they are from so long ago and they are so much better than what's out there now and even stuff you have to pay for and sit through a class on.

exactly i have noticed the same thing! And I am not from USA so proably it is the whole-world trend now !

I couldn't agree more. Showing the variable letters increase/decrease in size to balance the power equation is sooo informative. That has helped me so much imagining number relations when there is no pen and paper. Awesome teachers back in the day!

Very true. I don't understand why this kind of videos were not on my feed much earlier. This channel is doing great work.

Probably a reason for that.
These are some amazing videos 😊 Old is gold ❣️
Very informative video, all this thinking really drained me tho.
I feel the bit about the current reduction ratio is vital for the project I have in mind. Thank you for sharing
this video has inspired me
LOL I like how they use cycles per second (cps) instead of Hz, and P=IE instead of Watts=Volts*Amps. I''ve never seen that before.
Actually you CAN use a 50-Hz transformer on a 60-hz but a 60-hz transformer will over-heat on 50-Hz. 50-Hz requires more core iron than 60-hz transformers have.

And I didn’t think a A +\- 16% frequency change is anything more than negligible
Geniales estos vídeos..
Note this uses "electron flow" current direction. Not bad however in engineering/physics it is all explained using "conventional current flow" or charges moving from the + terminal to the - terminal of the battery. It actually makes circuits easier to analyse and design.
Damn i love that old timey music
I thought the mnemonic was "right-hand rule" and the field vector would be in the opposite direction? Did they mean non-conventional (ie electrons' flow) direction perhaps?
🤔 i wonder if they still use the psm-6 in the military
This was to train people working as engineers... either in a military sense (Seabees for naval logistics) or a civilian sense (Army Corps of Engineers).
great video
What I really wonder is, if I talked into the same microphone, would my voice sound “old timey” like his?
At least, this version of TRANSFORMERS haven't been directed by Mickael Bay !

wicked video
My God! It is now as easy as cutting Butter!
vtvm cool i had an eico and they do read backwards only thing the film dident cover is wire gauge this is inportant in current made or used also frequency
Did anyone notice the smirk on his face when he said a transformer couldn’t be operated at 60 Hz and 400 Hz at the same time
tell your son, we are going to see the new transformers movie!
Direction of magnetic field around a current carrying conductor is given by using right hand thumb rule(also called Maxwell’s corkscrew rule and not by left hand rule as shown here)...otherwise videos here are too good 😊
I assume by cycles per second he's referring to Hertz right?
@marcwerner7521

yes, cylces per second is the frequency which is measured in Hertz

American English generally speaking, was not as fast or choppy, and people spoke more exactly and used less slang. It was even clearer back in the 30s and 40s.

I think he was referring to power in = power out. Obviously minus efficiency losses.
is this how optimums prime works?
Unfortunately, you're rite.This is the advantage of the internet that these things can still be avail if u looking fo them without the need 2buy text boox, thus saving on paper nd always can find the latest most upto date stuff, thanx 2th internet.
i got here thinking it was the transformer of the movies like a hidden military conspiracy and how they really exist and shit i was dead laughing lol
It seems funny that it is from 1965 to me because I would have thought it was from 1940.
Did you live in the 1960s? Please tell me if you know; what was it about people talking this way? Was it a trained way of speaking or did everyone just tend to speak like this? I would call it an elegant way of speaking, like neat cursive handwriting. Why has it gone away?
I didn't know electricity was a military issue
Yes, even though I am only a teenager, I too long for America's more cultivated days.
I bet they are making them, but not for publics' eyes
Transformers. The begining. I didn't catch - where is Optimus Prime?!

Everyone need a smaller coil from time to time :-|
See 10:48 optimus prime is type #4
WE don't teach this clearly anymore..well our media anyway..
why dont people talk with that accent anymore
my teacher told me if transformer increases voltage, it also increases current, i guess it's my duty to show him this video so he doesn't tell other same bullshit
[metatron jokes] *meiks faáat souwndz*
not bad ,but very old lol
This is what they use to teach. In the US by time we come out of high school pretty much all we know is how to wipe or own ass and make a complete sentence. The type of knowledge we need to know to function in the real world is almost nonexistent. It is really just disgraceful.
