I could stick a heating element in an arctic iceburg and it will disipate the same amount of heat energy but the element could be 100 degrees colder because the ice sucked up all the heat. The main effect that a lower temperature per amp has is protecting the resistor from damage. | |

May 2, 2018 at 1:54 | comment | added | soundslikefiziks | @jameslarge but if that was true, wouldn't it cause batteries to lose the same amount of energy and discharge at the same rate regardless of the resistance in the circuit ? | |

No, you cant 'tune' the amount of power dissipated - but you can tune a resistor to more effectively radiate heat. Not all resistors with the same resistance and current passing through are going to reach the same temperature as your comment indicates. | |

May 1, 2018 at 22:20 | comment | added | Solomon Slow | You can't "tune" the amount of heat per Watt that is dissipated by a resistor. A resistor (including a purpose-built electric heating element) always turns 100% of the dissipated energy into heat* | |
