I have question about temperature graph of brake resister.
1. Does the excess temperature mean that how much rise from current temperature?
ex.) at 100%, excess temperature of resistor element is 300 K. So, if initial temperature of resistor is 25 degree in Celsius, 25+300=325 in Celsius is the resistors temperature?
2. Continuous dissipation - How long? Does it mean that resistor works until it reach the ultimate temperature?
