Do Led Resistors Get Hot at James Depew blog

Do Led Resistors Get Hot. Resistors work by converting electrical energy into heat according to ohm’s law, p=i2r. Even though the vres resistors are much better thermally than the previous gold resistors they can still get hot in some. Yes, it is normal for a resistor to get warm or even hot during operation as it dissipates power. With any single led having a forward voltage of 3 volts, four of them in series would equal 12 volts. The problem is that the supply voltage of 12v is much too high for a 3.4v/300ma led. If this is the case, then you must. You'll be at or exceeding the maximum power rating of the resistor which will make it very hot indeed. Even now with the 200w resistors. I was going with the 200w because on my tests the 50w resistor was going very very hot. For testing, i've currently just got one segment wired up with a resistor.
