Got 2 quick questions, one involving resistors and another involving an LED. I was digging through some old stuff a few days ago and came across my old stash of parts from a few years back. One of the things I came across was an old white LED and some resistors. my questions are this,
1: do LEDs and resistors have an expiration date such as they're no good after x amount of time. The resistors and LED are unused and were stored in a dry container for a few years.
2: can a 2.2 ohm 1/2 watt resistor stand in as a substitution for a 1 ohm 2 watt resistor.
just curious as this will save me a little bit of cash for a future build.
