Hair Straightener

Sign in to follow this  


As a part of my morning routine, I usually straighten my hair with the Paul Mitchell express ion smooth hair straightener (sounds fancy I know) that can heat up to 410 degrees Fahrenheit in 60 seconds. This is a pretty incredible feat that certainly makes my life easier, but I thought I'd explore a little more behind the straightener's ability. After doing some research, I found that the straightener has a rated wattage of 40W and the voltage of American outlets is 120V. After doing some calculations, I found that the resistance of the straightener to be 360 Ohms. This is a relatively low power rating and high resistance when you consider that the hair dryer that I use has a power rating of 1875W. Pretty interesting stuff that I can't quite understand. Feel free to leave any comments that could help explain this! Thanks.
