Hello and happy new year 2022 !
How to make a variable power load/consumer to test a single component? For example, I want to test a transistor heat resistance to load. I want to know at what wattage it will start worming up and then when it will heat up and then when it will boil up, near destruction. What is a cheap and efficient method ? I saw a youtube movie once with a power resistor, probably a 1 to 5W, but I dont remember the circuit or the exact context, I believe on the same 'load' testing board was a fan and a knob. I want a circuit or an idea, to make it myself with the components I have.
