Took apart a hot plate, nichrome is touching directly to the iron?

Click For Summary
The discussion centers on the surprising observation that nichrome wire in a hot plate is making direct contact with iron without shorting out. Participants suggest that corrosion on the iron and the element's "earthy end" may limit current flow at low voltage. There is a question about whether continuity has been measured across the contact point. Additionally, the possibility that the iron might actually be a non-conductive material like ceramic is raised. The conversation highlights the complexities of electrical conductivity in appliances.

Took apart a hot plate, nichrome is touching directly to the iron??

How is it not shorting out?

I can only suggest that it is the 'earthy end' of the element that's touching and the corrosion on the iron and the outside of the element are limiting the current passed at this low voltage.
Have you measured the actual continuity across this apparent contact?
 
Or perhaps the "iron" is actually ceramic, or something else non-conductive.
 

Thread 'Is this a coincidence?... (distances between planets)'

I'm not a student or graduate in Astrophysics.. Wish i were though... I was playing with distances between planets... I found that Mars, Ceres, Jupiter and Saturn have somthing in common... They are in a kind of ratio with another.. They all got a difference about 1,84 to 1,88x the distance from the previous planet, sub-planet. On average 1,845x. I thought this can be coincidential. So i took the big moons of Jupiter and Saturn to do the same thing jupiter; Io, Europa and Ganymede have a...
