    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™🛑

    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.

    Wouldn’t you want a lower resistance wire instead, since heat increases with current squared?

    • @quasar-ed
      @quasar-ed  19 днів тому +1

      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.

    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.
