Extension Cords: Thick One First Or Thinner One First?

Hello again,

The main point of this thread was to show how crazy 'ai' can be, and also address the question again.

What is missing from the main question is the operating conditions that some have started to mention. The 'ai' bot did not show any either so it's points are all entirely senseless. It would need to start mentioning some of these aforementioned conditions such nearer or farther from flammables, enclosed or open air, that kind of thing. Without that, the answer has to be that it does not matter which comes first. It's only when we impose those conditions that we start to see more logic in what should come first.

The response wasn't crazy or AI. Systems today are mostly autocomplete, selecting the next likely sequence of words. You feed it nonsense inputs, you get good looking nonsense. You feed it sensible inputs and still get good looking nonsense.

I asked the question on Google and got the same response in its AI summary, plug the thicker one into the wall.

It lists references when it answers a question. None of them had that recommendation, and most said you should never plug one extension cord into another, which is sensible since that might exceed the length allowed fir its gauge.

Yeah that's funny.

I've used extension cords in series but I knew the current would be low. If you can't use two 20 foot extension cords in series to power a 60 watt lamp, you really don't know much about electricity :)

Hey, A funny follow up question might be:
"How about if I plug a 10 AWG extension cord into an 8 AWG extension cord and use it to power my cell phone charger" :)

I just asked "Copilot" and it gave more reasonable suggestions except for a couple.
It did mention that you have to watch the voltage drop and power rating of both cables.
The exceptions to the reasonable suggestions were:
1. "A 16-gauge cord is thicker than an 18-gauge cord. So, when you connect them, the thicker cord (16-gauge) will carry the load."
2. "If you’re running a hairdryer or a toaster, no worries—a 16-gauge and 18-gauge combo should handle it."

Both of those are really stupid idea.

It did give some reasonable results though I was surprised this time.

The #10 extension cord should be first so that the voltage supplied to the second cord will be a bit higher. The voltage drop in the second cord will be subtracted from the higher voltage at the end of the heavy cord. But the difference will not be very much.
And consider that the AI bot can only base it's conclusions on whatever it uses as a reference, obviously the yellow cord will drop less voltage than the black cord.

You should have asked whether a black cable has better heat dissipation than a white one :p
Depends on whether the extension cords are used in bright sunlight or at night.
In bright sunlight, the black cord absorbs more solar energy and gets hotter.
At night, the black cord emits more black body radiation and runs cooler.

And is it a flat cable or a round one (more surface area) ?
and is the insulation PVC (0.17W/mK) or butyl rubber (0.23W/mK)?

I've got to side with the bot.

You all here do have correct answers, but remember AI pulls information from what it finds on the 'net. You'll always want to double check info from different sources, even if your grandparents say your 10mm socket came from Santa... *that might not be true*.

Besides, if one doesn't like the replies from an AI bot that scoured its answers from the human WWW, I'd blame the humans that incorrect searches came from, and/or the sad state of the education system(s).

So go attack TikTok! Double, ney triple check your sources. Always.

That is nonsense.

AI bot gets its information from the internet. There is a lot of nonsense on the internet.

Garbage in => Garbage out

Think about this. One AI bot gets it wrong even if some of the humans provided the correct answers.
How many other AI bots would give higher credibility to another AI bot than to humans?

Giving credibility would infer some type of ego.

What AI has an ego?

What Ai even acknowledges other AI? Ask ChatGPT what Gemini is - has no idea, won't even entertain the corrected answer.

Ego? Or human programming instructing it to deflect questions about competitor AI?

Who knows? Who cares? I ask questions, then always double check its answers.

So you double check the answers? With what source?

Why bother to ask the question in the first place if you already have a reliable source?

In other words, you already have two reliable sources that are in agreement?

What if your two reliable sources are not in agreement?

What reliable source should I be asking?

You? Your grandparents? Homeless ex felon on the street corner?

I check multiple sources, actually - gotta do research the scientific way. But, if you are the All Knowing One, I can just come here and ask you (and your [biased] attitude) personally.

Can I just stop by your place and have a chat? What's your phone number?
