RE: The War of Currents and the Birth of Inverters

in #stemng7 years ago

Howdy churchboy, how goes it in Nigeria?

Good post once again, though......of course I have something to add.
I believe one of the biggest differences between Edison and Tesla was that Edison was a thief, he contracted with Tesla, Tesla fulfilled his part much to Edison's surprise and Edison refused to pay him. Conversely, Tesla upon hearing the contract he signed with Westinghouse would result in employees being fired, Tesla tore up the contract. Edison was very much about his own fame and wealth, Tesla was trying to serve humanity. In fact, the two could not be more opposite if one were white and the other black. Tesla is a hero while Edison to me is an arch-villain.

"It was this Rock 'n Roll band that popularised what is known as the War of Currents" ~ I think you may have meant to say something else. The RnR band ACDC did not, as far as I know, and I could be wrong, take their name from the War of Currents of seven decades prior. In the 1970s England, someone who was ACDC was bisexual and it was that slang usage that the inspired the band to take the name ACDC.

I also question your switch light analogy. Switching an AC power source off and on at 50 times per second I doubt would produce direct current, perhaps if you were able to cut the wavelength in half and disallowing the negatively charged pulse, but that would require some serious timing with that magic.

And the frequency that you speak of 50Hz and 60Hz is actually speaking of the properties of the magnetic wave. All energy on the electromagnetic spectrum has a frequency(Hz) and a wavelength(meters)

In this chart, you can see that radio waves are in the millions of Hz, much much higher than electricity at 50-60Hz which is down in what is called the "super low frequency" and has a wavelength around 10,000,000 meters in size. The larger the wavelength the lower the frequency, the smaller the wavelength the higher the frequency. For example, Gamma rays at the opposite end of the spectrum have a wavelength of 1 pm (picometer= 0.0000000000001 meter) and a frequency of 300Exahertz. 1 Exahertz is exactly one quintillion Hertz. 1 EHz = 1 x 10^18 Hz.

So electricity at 50hz means that wavelength of 10,000,000 meters passes (peak to peak) a single spot 50 times per second.

Alternating current means the current alternates direction, while Direct Current can only flow in one direction. In other words, AC switches from V- to V+ to V- to V+, while DC is V+. One revolution you see in an oscilloscope such as the image down below equals 10,000,000 meters in length.

As you can see by the above image, DC has a wavelength too.

Peace brother

I should have known I was in for a surprise tutorial when you suggested last time that I should talk about the history of those two inventors. I was not there at the time but everything you wrote about the feud between Tesla and Edison seems to be spot on. Yes the story has it that Edison tried various dubious means to win the war. And yes, the two inventors couldn't have been any different, even their pictures say so.

When I say that ACDC popularised the war of current, I meant that the rock band is the only ACDC that most ordinary people know. The war of current is not a general knowledge. However, I am glad that this has made you talk about the bisexual connection. I did not know this prior to reading your comment.

Concerning the 50 Hertz, I thank you for the electromagnetic analogy. I'm sure you meant to point out that magic hands are not enough to convert DC to AC and I agree. That's why we use pure sine wave inverters :)

Now, let me go and look for steem power to upvote your beautiful comment because my steem power is hardly enough :). Thank you for the time you spent explaining these things. You may have just inspired another post.

Oh, we are doing very well here in Naija :). How are people of the earth? :)

Well, I am happy that you received my "surprise lecture" with the goodwill I intended when I wrote it.

Concerning the 50Hz, that isn't an analogy as much as it is accepted science. I know there are differences regarding electrical theory between electricians and physicists. I assume you are coming at it from an electricians perspective. I myself only started studying electricity a couple of years ago as I became fascinated by the electric universe paradigm and wanted a deeper understanding. Since then I have read a great deal on Maxwell and Faraday, Hertz, Steinmetz, Tesla. Have studied it from the Physics perspective and the electricians perspective(IEEE). The problem with the physics is they rely too much on maths and not enough on real-world observation.

It pleases me greatly to have inspired you, that is truly a special gift; inspiration that is. I enjoy reading your posts and in particular, this line of communication opening up between us.

In my part of the Earth, it is cold and snowy. Would you say your weather is cooler than normal, about normal or warmer than normal?

Peace
