AI Thread Summary
ChatGPT has gained attention for its ability to answer complex engineering questions, but users have noted its occasional inaccuracies. While it can provide valuable insights and methodologies, reliance on its answers without verification can be risky. Users emphasize the importance of critical thinking when interacting with AI, as it may produce incorrect information. The chatbot's responses can serve as a starting point for deeper exploration, but caution is advised. Overall, while AI can enhance learning and efficiency, users must remain vigilant about its limitations.

TL;DR Summary
Playing with chatGPT to do some calculations is kind of humbling...
This chatbot has been getting a lot of notice lately - my son, a mech E and I were throwing a variety of questions at it, and then with a bio-chemist last nigh at dinner ( geeks - yes) - anyway. It fun but also makes you feel a little obsolete... I threw a magnetic / induction question at it that I could find anyone to answer and now I have to re-think some issues!

lol

It is remarkable. But it is still at the stage where it sometimes gets the answers completely wrong. But expect it to improve greatly in coming months.

But that makes a good lesson for all of us dealing with any AI. It can ease our jobs. We can learn from it. But we must be on guard for completely wrong answers. Anyone using it who is not capable of detecting the AI's errors is a fool. That statement may remain true no matter how good the AI gets.

I appreciate that it gives the methodology of the solution so you can work through it. The answers can be at "executive summary" level, but it does allow you you to continually query the answers and dig deeper. I have to check on a wrong answer and ask it to explain what the difference is between the correct answer and the ChatGPT one... would be interesting.

Luckily - our language is schematics - and not easy to input, well there is netlist. ( It apparently does not have acess to LTSpice models...)
 
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
