This has been bugging me and I just can't seem to figure out a solid answer.
My electric stove has different sized heating elements where the size comes from just a longer heating element. It looks like this:

When I measure the resistance of the small one I get ~45 Ohms, whereas, the longer one has ~26 Ohms.
Intuitively, you would think the longer coil would have more resistance so I'm trying to understand why this isn't the case.
My current two theories are: (1) a different concentration of doping materials are being used (which doesn't seem like a very efficient manufacturing process) or (2) the diameters are different inside the black coating (which doesn't seem right either).
Anyone know the answer or have another idea?
