Today, I stumbled across a #Udemy course on #ElectricalEngineering—a $37.98 online course, purportedly a single bundle that will give one "everything" necessary to reach all the goals in a licensed #engineering profession.

This probably is an #AI-generated lecture set. I am deeply #troubled, to say the least....

I still recall the day several decades ago when I, as a young #ElectricalEngineering undergrad, was introduced to the concept of "negative #frequency". I was unsettled. I suppose my reaction to the idea of negative frequencies was like the Medieval mathematicians' reaction to Fibonacci's discovery of negative numbers. But after my head was properly bashed in by a couple of homework problems, this concept became as natural to me as the negative number and the negative time.

I am curious how civil, mechanical, and other engineering fields deal with the concept of negative frequencies.

Marc-Antoine Parseval, born OTD in 1755, devised what is now called Parseval's theorem, a precursor to the Fourier transform https://cromwell-intl.com/travel/france/electricity/?s=mb #travel #France #ElectricalEngineering

(a emergency and critical items fund) Can someone help us with:
Food (100 usd to be set for a bit)
Car windshield wash (4-16 depending where you get it from)
Bus engine coolant (it drinks coolent) (17-18 usd)
12v 100ah lithium ferris phosphate batteries with Bluetooth for power monitoring and power management for more stable power for our solar on our bus as we use it for cooking and surviving and more batteries means we can draw more power and have heating and cooling as well as charge car and let others in need use it and more batteries means the load is spread out more so less chance of electrical issues (every battery has to be the same and we can't mix chemistry nor voltages nor storage capacity on individual batteries) (200usd including shipping per battery)

So, I would like to #crowdsource a solution to an #ElectricalEngineering #EV problem.

I need to safely split a J1772 split-phase input into two parallel chargers inside a project vehicle. Each charger is capable of 3 kW. How would YOU do it?

French scholar Pierre-Simon Laplace, born OTD in 1749, developed the Laplace transform which is used in many branches of mathematical physics including #ElectricalEngineering https://cromwell-intl.com/travel/france/electricity/?s=mb #travel #France

Just had a brain fart here.

If there is a fault on a bus with motors running, those motors will at least momentarily contribute current to the fault - acting like generators.

Am I correct that this would happen with both induction and synchronous motors?

I’m also wondering if this can happen through a VFD - I’m guessing that depends a lot on the topology (and how quickly the fuses blow). #electricalengineering #electricity

Meanwhile on Discord…

“How do I show the impedance of a fang is it a resistor with an inductance in series?”

This has to be one of the strangest electrical discussions I’ve ever hard… #electricalengineering

Georg Ohm, who discovered the direct proportionality between voltage and current, was born OTD in 1789 https://cromwell-intl.com/technical/current-box.html?s=mb #ElectricalEngineering #history

Georg Ohm, who died OTD in 1854, discovered the direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current https://cromwell-intl.com/radio/copper-wire/?s=mb #ElectricalEngineering #history

Wait, this was more interesting than I thought. With a high enough current, the Lorentz force can compress a conductor so that it doesn't vaporize due to the extreme current. This means you can make a directed lightning weapon that works like a taser.
