Resistance
Resistance changes with temperature. There are three circumstances under which resistance can be measured:
1. Room temperature (before use): nominal ohms are
90% of Ohm's law calculation.
2. Room temperature (after use): nominal ohms are
95% of Ohm's law calculation.
3. At temperature (during use): depending on application
nominal ohms are approximately 100% of Ohm's law.
Note: Resistance and wattage values are approximate depending on application conditions
