10. For a resistance at a temperature other than 68°F or 20°C, use the following formula. Note that
these calculations are for copper cabling only.
For temperatures in Fahrenheit:
R
TF
= R
68°F
+ [ 0.0022 * ( T
F
- 68°F ) * R
68°F
]
Where R
TF
= new resistance based on new temperature in Fahrenheit
T
F
= new temperature
R
68°F
= resistance of the cable @ 68°F
