Can you use the huge 50w load resistors for hyperflash to trick airbag lights?

[Adieu]

Or will they overheat somehow?


Yeah i failed college physics. Repeatedly. As you can probably tell.


PS im not asking about ohms, 2 in parallel should generate 3ohms a pretty close value to what is needed..

Im asking about heat... will 50w resistors generate more heat than 0.5w resistors?

will 50w resistors generate more heat than 0.5w resistors?

Yes. 100 times the heat, since they aren’t doing anything with all that energy except dissipate it as heat.

If it has a sufficiently large heat sink and is in a cool enough place with sufficient airflow, it will operate as designed, probably. What resistors are you planning to use?

No need, I found a 2.2ohm 0.25watter that worked just fine. Mostly just wanted to know if I could try them to experiment with different values or if I couldnt find that 2.2ohm tiny one or if it hadn't worked...and for future reference

Its on a bimmer not the expy though... that thing had the stupid exploding headrest gimmick, which has been throwing codes and and 6 different naglights and flashing warnings on a whopping 3 different screens --- can you say obnoxious???

Just as an FYI, a 50 watt one ohm resistor will produce the exact same amount of heat as a one watt one ohm resistor if put in the same circuit. The wattage rating is the amount of current flow (heat) the piece can withstand not how much it produces.
