Artificial Intelligence Not So Intelligent! AI Flunks the Parallel Resistor Test!

So this morning I asked this of AI:      

How should I make a 50 ohm dummy load capable of handling 5 watts from 330 ohm 1/4 watt resistors?'

Here was the answer: 


Oops.  Nope.  That makes a load of about 20 ohms, not 50.   

Wow,  this seemed like a fairly simple request.  AI got it wrong.  If AI (LLM) can't get a simple question like this right, you have to wonder how many other things it is getting wrong.

  1. I'm not sure if the AI has got through the licencing exams yet. Some of the circuit diagrams it comes up with are 'experimental'. HI HI HI

  2. I think it would be nice to know which AI model you used. Asking ChatGPT and Claude the exact same question gave me the correct answer.

    You can also give it directions to “think harder” or to be sure of its answer and not guess.

    1. I just plugged the question into Google and selected their "AI overview."

  3. One thing of learned is different ai LLMs are better at some things than others. The scary part is the will sometimes be completely wrong but sound very convincing. One of my current favorites is Grok expert mode. I submitted your same question and the response can be found here:
