[@brunopacifico4979]

[@alext8828]

It's not complicated enough. They had to make the arrow point to the south pole of the coils instead of how a compass is arranged pointing to the north pole? Is there a plan afoot to mix us up? Come on, people. Why do that? Just another small pebble in the road.

[@alext8828]

What's with the dynamo @ 4:37 "...Galileo Ferraris used an inductor in one of the two coils supplied by a single-phase ac dynamo later..." This video is confusing.

[@alext8828]

@dasara doodla Yeah, I know that and you know that, but that's got no business in a 101 course. This is bs.

[@alext8828]

@Caishen Salelius 6022 My physics professors did not confuse us. There's another animated video out there that should be good too but suffers from the same thing. Too many moving parts with captions and narration. And music and sound effects. Interesting thing about knowledge and teaching. I think I'm seeing a good video or lecture when they explain things that I know already. But on further examination, I find that the explanations sometimes fail to explain clearly, things that I haven't learned. Our judging system is skewed a bit and tells us things that may not be true. PS. sorry this is so windy.

He was no doubt a great inventor but there’s a lot more people who developed ideas much higher in technology

[@nadronnocojr]

Astonished? I’d say disappointed , all this 100 years ago and we did nothing new with it, we barley improved on his , And now we cheapened it all for bottom line profits making sub standard everything. in fact he had 100’s of more viable solutions for not just electric motors , but vast amounts of technology.. we are light years behind , had he lived another 100 years we’d be using more than 10% of our actual brain power , and we’d be wasting less, and needing less ...... I think he’d say , I gave you the world and you came up with wireless porn ..

[@staringgasmask]

@@nadronnocojr we do use more than 10% of the brain power, but whatever. Only imbeciles complain all the time, he wasn't, he would work and try to improve. He wasn't a politician, he was an engineer, and those don't start whinning when things don't go as they want

[@keremsahin5482]

I fell in love with this youtube channel. Many thanks for this video.

[@connorfisher1651]

Tesla built the first a.c motors, but Charles Steinmetz, head of the original General Electric research laboratories, made A.C power transmission engineerable with his mathematics and theory, and therefore made the use of A.C possible. Before that Oliver Heaviside took Maxwells equations and simplified them to four short expressions; Maxwells equations as we are taught in school should really be called Heavisides equations. He also made telegraph transmission possible by describing the mutual relationship between magnetic and dielectric fields. He showed through his telegraph equation that the problem with telegraph transmission was not solvable by loading the system with more power, but was only solvable by intoducing loading coils at certain intervals along the line. Just a few names no one hears anymore.

[@geovani60624]

in my opinion the 3 phase wiring is more of an evolution than a revolution to the design tesla created, not to say it wasn't a big deal, but they just used what tesla had already figured out and improved it to make it more efficient

[@TrollMeister_]

Even the two phase was an evolution of Bailey’s original step change design. The fact that you could have a single vector and have that move, whether in stepwise or continuous fashion, by altering the current was his idea.

[@starboy001]

What will happen if we increase phases? Like from 3 to 4 or 5? Is it possible? If not what are the limitations?

[@geovani60624]

@@starboy001 I'm pretty sure the eddy effect will increase or simply not be beneficial enough to be viable

[@Itzzmeagain28]

Wdym? Tesla wasn't the only one to figure it out. Did you not watch the video. Ferraris had figured it out as well. Give credit where credit is due. Only thing that Tesla did different was patent his idea whereas Ferraris did not.

[@Itzzmeagain28]

And as a matter-of-fact Ferraris and Teslas design was an evolution in RMF to Walter Bailey's original design, so...🤷‍♂️

The key to understanding this is the notion of induction. Anytime a current is passed through a wire, a magnetic field in “induced “ in the opposite direction. Electric motors Make use of this “induced “ field by getting it to do work. It is one of the coolest phenomenons in nature.

[@Chopper153]

When a current is passed through a wire, magnetic field is not induced in the opposite direction, it's actually induced in a circular path according to right hand rule.

This may be off topic, but I think someone might find it interesting. :) Device to end the creation of Nuclear waist. Electric Generator Design that's powered by it's self & perpetuates more electrical current then is needed for it to run continuously on it's own. Step 1: calculate how much energy you need pumped into an electric motor to make a vertically positioned circular platter with magnets in-bedded horizontally around it's left side and right side (so there pushing force is pushing out sideways relative to the vertically spinning disc) to spin as fast as you need it to. Also better to make sure these magnets are shielded around their sides & back with metal that has high permeability so the magnetic field they are emitting is focused fully out sideways. :D Step 2: Calculate how many sets of copper coils you need to be interacting with magnetic fields to achieve this & to perpetuate more electrical current flow then is needed. :D Step 3: Build a round horizontally positioned platter covered in all these copper coils pointed down that does not move (Is stationary) :D Step 4: build a round platter covered in powerful magnets pointed up that can spin and place it directly under platter with hanging copper coils. :D Step 5: Position the vertical platter that is motorized close to the horizontally positioned platter covered in magnets pointing up so that when the vertically positioned platter spins the in-bedded horizontally positioned magnetic fields slam sideways against the edge of the horizontally positioned platter causing it to spin. :) Step 6: Make sure enough of the copper coils are feeding their electrical current into the electric motor and the rest of the copper coils are linked into a set of rechargeable Battery's placed in the closest most convenient spot. Step 7: Build a duplicate setup of horizontally positioned discs with hanging copper coils and disc with upwards facing magnets and assuming the first set of discs are positioned to the front left side of vertical spinning disc, position the other duplicate structures to the front right, the back left and the back right of the vertically positioned motorized disc. As the vertically positioned motorized disc spins the horizontally in-beaded magnets will now hit into all 4 horizontally positioned discs causing them to spin. so you will effectively be using the spin of one disc powered by one electric motor to spin 4 constructs that are each generating electrical current. now build this whole setup multiple times over and use the current perpetuated by it to power up scaled electromagnetic generators that are equal to or more powerful than the ones used in a nuclear power plant. You will now have a device that is self perpetuating off of it's own electrical current perpetuation and no nuclear waist to worry about.

[@ankitvatsa2665]

Please make a video on Cold start and Hot Start of old diesel engine. In old cars we have to push heat button first for some time then it will start.

[@peglor]

You still have to do that in new cars, just leave the key in the on position until the glow plug light turns off and then start as normal. This is because diesels are compression ignition engines (Rather than spark ignition like gasoline or CNG/propane/butane engines), so the heat that causes the fuel to begin ignition is created by compressing air in the piston (It gets hotter because as the piston moves up, a fixed mass of air is compressed into a smaller area, packing the energy in that air more tightly, which manifests as a higher temperature - this is one consequence of the ideal gas law PV=nRT - expanding a gas will make its temperature reduce too, which is the basis for refrigeration systems). When it's very cold, the combination of a cold engine block and cold air being pumped through the engine mean the ignition temperature of the diesel is not reached, so when the fuel is injected it doesn't ignite. The glow plugs heat the engine block enough to allow ignition to take place. Once the engine has started it generates more than enough waste heat to warm everything up enough to keep running without further electrical heating. Cold weather also makes the engine oil thicker, so the engine is harder to turn, and reduces the battery current available to the starter, so these also contribute to cold starting issues in gas and diesel engines.
