They usually put the ground pin on the outer ring where it can be touched. A metal rod doesn't get hot because the current is limited by the narrowest part of the circuit somewhere else. Less resistance means more power. The automatic switch relies on steam being driven down a tube. The metal grill in the spout helps with that. If that grill is removed, then the autoswitch won't react for some time. As long as there is water inside, the temperature will be limited to 100°C. Early kettles didn't have any of that and worked just fine. See a soviet coffee percolator.
@@j7ndominica051 Are you sure we are talking about the same kettle? It is true that the switch on the handle get the heat from the steam. But the steam doesn't need to go down to the bottom thermostat and there is no tube for that in this design. Because the bottom thermostat is placed just a few millimeters from the heat plate. So it can directly sense the heat without relying on the steam. The one you are mentioning might be built differently.
No, I've not seen this particular kettle. It possible that it is built as you said. I took the animation more of a schematic of a generic kettle, not a specific model. The plastic grille easily breaks. And there is video on UA-cam (I can't find it) where he demonstrates the effect of taking it out, allowing the steam a fast exit path.
The MAJOR problem with these kettles is the contacts prematurely burn out ..... most folk then chuck out the kettle , they can be bypassed ( care ! ) , but then the kettle MUST ALWAYS be attended whilst heating 😝.... but doing this gives another 10 to 20 years life , before the element burns out .. ( tried - n - tested ) ............ DAVE™🛑
@@demiundefited1768 Yes, I plan to. But I would start with videos about clutch and gear boxes before making one about automatic transmission. Glad to see your suggestion.
Kettles do not switch off because a thermostat. If they did, the temperature would be the same and it will boil too high or too low depending on the altitude. It is a small tube that fill with vapour what stops the kettle. Try a kettle with the lid open, never stops.
@@miguelJsesma The kettle you mentioned is different from the one I use in this video. Cheap kettle like this will never come with that fancy feature. Of course if the lid is opened, there is no way for the heat to reach the thermostat and the switch won't trigger.
In case of heating, we want more heat, so more resistance is better. For conducting wires, we don't want heat, so the lower the resistance, the more efficient the energy flow.
Most of the type electric kettles available in India are made in China and labeled as made by Bajaj Electricals of India. Such is the business these days made in India.
I'd be remiss not to mention this Steve Mould video: ua-cam.com/video/VzqN4Cn8r3U/v-deo.html Some kettles work in a smarter way, where instead of simply having a bimetallic strip that responds to the temperature of the *liquid*, a tube carries vapour from inside the kettle over a bimetallic strip. Only when the liquid boils, and the vapour pressure increases considerably, does the tube carry enough vapour to heat the bimetallic strip to its trigger point and switch the kettle off. That means that such a kettle responds to boiling in general, and not just the temperature water boils at at standard atmospheric pressure, so it'll work even if you use a different liquid, or take it to a high elevation where the boiling point of water is reduced.
@@jimgoplayoutsideable I will look into it. I hope there is enough data to make sense of how it is worked. If there was, I'll be sure to make an explainer.
Sorry but your video has not explained how the thermostat knows water has boiled. The video has needless details that offer no benefit except pushing the video longer than 10 minutes.
@@vedant2791 In this type of kettle, yes. It is made to be cheap , so it won't care for the tiny percentage of consumers who live on mountain. And what is so bad about boiling at 100 degree C on mountain. Do you want to cook longer with low boiling point? You do realize these "atmospherically correct kettles" are just for marketing purpose, so that they can charge more for little unnecessary feature.
@@vedant2791 And don't get frustrated if you don't understand something and act like explanation is bad. You just don't have the right basics, so you keep learning until you understand. Good Luck.
@@quasar-ed hahah you’re caught with pants down and no understanding of how a thermostat knows that temperature of water has reached 100 degrees Celsius.

Smooth. Mentioning quantum mechanics in a video about water kettles. Well done 😊
@@driesindesteege2990 Well if I don't, people might complain that "this is not how electrons behave or something".
I love how a type F plug is plugged into a type G socket.
oh come on. it ain't a video about sockets.
just push harder, it will go in
Lucidly explained. Wishes from India.
Your videos are very good for understanding basic concepts.
Thanks for uploading
Well done
Always wanted to know how these work.
@@JGambrosia Glad you found it helpful. Thank you.
Nice and informative❤

When the dielectric collapses, it becomes dangerous. In general, electricity and water are enemies.
@@yakut9876 true.

I also took apart a broken kettle with the same internals as the one in the video.
Idk if its to mush work but how about you make a video about a clutchless transmission
@@demiundefited1768 Yes, I plan to. But I would start with videos about clutch and gear boxes before making one about automatic transmission. Glad to see your suggestion.

Wouldn’t you want a lower resistance wire instead, since heat increases with current squared?
In case of heating, we want more heat, so more resistance is better. For conducting wires, we don't want heat, so the lower the resistance, the more efficient the energy flow.
Nice but aint there a rule you need to warn upfront your video is sponsored instead of at the end?
I checked the 'includes paid promotion' checkbox when I uploaded the video.

Yeah, this video is what came to mind when I saw this mechanism.
@@Redingold Gonna check that out. Thanks.

Because water boils at 100 degree Celsius.
@ does water boil at 100 degrees Celsius event when atmospheric pressure is low at mountains? Lol.
