Why is the water inside the kettle not electrified?
In: Physics
The heating element is usually insulated from the electricity in a kettle.
[Here’s a video of a water heating element](https://youtu.be/JkNdM3TRZs4) being cut open. It consists of the heating wire, some insulation powder and then the outside metal tube.
There are some countries that use non-insulated heating elements to heat water, such as in [this shower head video](https://youtu.be/cNjA0aee07k?t=318)
And some countries use devices that use the water to conduct electricity between live and neutral terminals, such as in [this water heater video](https://youtu.be/EViyccc2t9w?t=206). The water has high resistance, so the electricity heats the water as it passes between the electrodes.
