JLN's  W Filament  2.5E-4 meter dia x 0.100 meter long
 
Area = (pi)R^2 x L   =    4.9E-9 meter^2
 
Correction:  Area = (pi)D x L = 7.85E-7 meter^2
 
Resistance at 27 K  =   0.122 ohms
 
Resistance at 500 K =  0.203  ohms
 
Resistance at 1,000 K  =  0.508 ohms
 
Resistance at 2,000 K    =   1.13  ohms
