I was toying around a bit, wiring up some LEDs and connecting them with the resistor that came with them to the transformer.
Well, the LED works and I found out that LEDs are a nifty little way of determining the polarity, but I happened to burn my fingers when I touched the resistor - It was bloody hot!
So is it normal for them to get rather hot or should I be careful with them, as I would rather not have it causing a fire? Might I be using the wrong resistor?
