It only takes a minute to sign up. @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 ? Check out our Heating element is a component intended to "waste watts" as a primary function, but it acts as a resistor as a side effect. Characteristics of PTC thermistors Switching PTC thermistors are usually made of poly-crystalline ceramic materials that are highly resistive in their original state and are made semi-conductive by the addition of dopants. I've seen at least one ovenized oscillator (where a tiny oven is used to keep one component at a very specific temperature) that simply used a resistor as the heating element.

Electricity flows particularly well through the components when their temperature is low. Mutually exclusive execution using std::atomic? Voted Is there a solution to add special characters from software and how to do it. These materials have a critical temperature where the resistivity changes quite markedly. If you can characterize the resistance vs temperature of the heating element, your controller could have a separate mode where it initially limits power on startup until you reach some temperature where you know that the resistance is such that the controller turning full on or 100% duty cycle on your PWM will not draw more power than is acceptable to you.
