  • I think both of you are right. If you have this same current at 3.3V and at 5V difference in power is proportional to the voltage, but if you have this same resistor and put 3.3V and 5V on it, power consumed by resistor will by with current2 and it will be ~2.3x less power at 3.3V

No public wish lists :(
