- We all know Thomas Edison, his accomplishments are legendary, over 1000 patents were issued to this prolific inventor. Nikola Tesla, noted Serbian academic, was another inventor from the same period, trained in Europe as an engineer, he emigrated to the United States where he never attained the stature of Edison but arguably accomplished more. He is the inventor of our modern electrical power grid. This video summarizes this accomplishment and the role that both Edison and Tesla played in this accomplishment.

I first heard of Tesla when in high school (over 40 years ago). In college, I built a Tesla coil for fun. Today, I have made certain that my children know who this person was and what he did for us. Unfortunately, his accomplishments are still not well known by the masses.

Brilliant video as always! But there is only one thing I have to disagree. It's almost irrelevant but, Tesla's vision of modern electricity was that everyone have free wireless electric power witch he did in public to show that it is possible.
It would be great video if you could make one with explanations of wireless electric energy. :) Thank you for all your great videos!
one of the very few channels i appreciate spending my time on...
It always makes me wonder and start a research on something...
4:05 Electrons actually physically flow from the negative side to the positive side. Although everything is commonly done or calculated with conventional flow (plus to minus).
Brilliant video! Learnt more about AC vs DC in 10 minutes than from the boring science classes I had when I was a student in the late 80s in Singapore. Excellent presentation as usual. Just the right pace. Not too fast, not too slow. America needs more Science Educators of your calibre.
Very informative, thanks.
Thanks for the video. The difference is much clearer now
great. thank you.
The best explanation seen. No other one need. Thanks
Love the videos! How science is put into perspective. Engineering and sciences are amazing and life-changing, I am probably not smart enough to do them, but I love them.
enjoyed it and learned a lot
I am confused slightly. Voltage is like the speed of which charge travels to either poles, so if you have a low Ampere, high voltage circuit, you would still get a fair amount of coulombs passing a cross section of conductor per second resulting in much more amps? Or is it that the more voltage, the more joules are released resulting in more efficiency yet a low current?
Great video with a nice addition of the history behind AC and DC
great of u thanks a lot man!
excellent clip
Thank you for this..excellent again!
Then light energy become heat energy. But that was a smooth steam engine. But still Edison invented light bulb, so both are great =)
AC DC!
i get my breadboard in tomorrow!
Emagnetic Inducer/Repulsor coming soon!
*maniacal laughter*
This work is highly appreciable esp. because i get to know such great aspects of a thing as basic as electricity,absolutely free of cost.......thanks scienceOnline....
thanks Tesla thanks Edison
thank you ScienceOnline :D
DC is making a comeback!
Imaging doing all that to read a book at night...
How can you calculate the power in an AC system??
Thomas Edison didn't invent a thing. Thomas Edison was a nobhead !
Nowadays high voltage direct current is much more better, less power loss and even cheaper then AC. There is a chance DC could fight back!
Science won! You people make Amazing videos
Yeah, I'd like to see ads at least. I mean... I dont want ads, but they are everywhere and I could easily stand an ad before quality videos from ScienceOnline.
well, at least this was a better visual explanation of AC. The concept of obtaining higher current through lower voltages is still a bit fuzzy.
You know Brady too? :D
We dont have this pole in Sweden :D
to correct your description: tesla wasn't trained in serbia. he was ethnically a serb but he was born and lived in croatia and as far as i know he never visited the region where serbia is today. before leaving for the states he was trained in graz, budapest, vienna and prague which had the best universities in the austro-hungarian empire. it's like insisting obama is keniyan or something. who cares and what's the point?
tesla is born in serbia but he studied and lived in croatia
Tesla > Edison
On what grounds do you state you comment? Perhaps you're only jealous there's nothing original about you, including your name.
