Good Evening,
I was reading about
Robert's Heated Bed and about
Conductive Materials but I didn't find how he calculate a resistance of 1.3 Ohms:
32 loops x 220mm = 7040 mm= 7m
R
s=0,0168/1,5= 0,0112Ohms/m
R=0,0112*7= 0,0784 Ohms
and with the other wire value given in the post:
R=7(0,0168/(3,14*(0,56/2)
2))=0,47 Ohms
What did I do wrong?
