My neighbours threw an old Proctor-Silex T2 automatic pop-up toaster in the recycling bin this morning. It was there when I returned home this evening so I snagged it. More nichrome wire for my DIY dew heater projects!
§
The long wire has a resistance of 43.8 ohms. It is 170 centimetres long (that's about 26 ohms / metre). One of the short wires comes in at 14.2 ohms; the other at 13.1. They are both 100 cm long (so around 13 to 14 ohms / metre). I noticed that the short wires are thicker or wider than the long ribbon, about 50% wider.
The higher resistance explains why these wires are shorter than the ones from the older toaster. That's 10 or so years of nichrome technology, I guess.
