AI Thread Summary
Steam irons convert electricity to heat primarily through nichrome wire, which acts as a resistor that heats up when electric current flows through it. The generated heat is then conducted to the flat plate using metals that are effective heat conductors. To ensure safety, the electrical components are insulated from the iron's exterior by a non-metal that conducts heat but not electricity. The heat power can be calculated using the formula: Power = voltage squared divided by resistance. For instance, with a voltage of 110 volts and a resistance of 12 ohms, the heat power output would be 1008 watts.

How do steam-irons/flat-irons directly convert electricity to heat?

Nichrome wire, typically. wikipedia.org has a reasonable write-up on it.
 
Steam irons etc contain a large resistor which gets hot when electric current is passed through it.

This heat is conducted to the flat plate by metals which are good heat conductors but the electricity is insulated from the rest of the iron by a non metal which is a good electrical insulator (but a good conductor of heat.)



You can calculate the heat power generated.
The unit is the WATT.

Power = voltage times the voltage, divided by the resistance of the resistor.

For example if the voltage was 110 volts and the resistance of the resistor was 12 ohms, the heat power generated would be 110 * 110 / 12 or 1008 watts.

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Where is my curb stop?'

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
