Resistance
What is the resistance of 85 feet of #2
90°C copper conductor?
Steps Keystrokes
Reset calculator [Set] [x]
Set to 90°C mode [Set] 9
Enter wire size 2 [WireSz]
Find resistance [Set] [Length]
Find 85 ft resist* [÷] 1000 [x] 85 [=] 0.0172889
*NOTE: Given resistance per 1000 feet,
divide by 1000 to get a per foot resis-
tance, then multiply by 85.
