WebThe purpose of a resistor is to convert electrical energy to thermal energy. This reduces the electrical energy applied to other portions of a circuit. So if you are going to push current … WebMar 11, 2024 · Resistive element burnout occurs when a resistive element is exposed to an excessive load, ESD, surge pulse, etc. The mechanism by which resistive element burnout occurs An excessive load, ESD, surge pulse, etc., causes a large current to flow instantaneously through the resistive element, generating heat as a consequence.

WebThe derating curve means that if you run in a 70C ambient temperature (air around the resistor) you can use 100% of the rates power (5W) but if you’re in a 155C ambient, you can only expect 50% (2.5W) before burning out the resistor. Your resistor will be able to melt solder before it burns itself up. I wouldn’t worry about it getting too hot. Web10V to 3.3V through a 10 ohm resistor is still 670 mA which is enough to burn out any microprocessor. You'll need a little more than 10Ω, try 10kΩ then you would get 6.7mA which would probably be acceptable in most applications.
