Is there a way to go from 110v to power an LED that is rated to 3v? Can I use a resistor? Bear with me, I am still trying to figure out all this electricity stuff. I could seem to find what i was looking for in my searches so far. Thanks in advance!
Pretty sure you want 3V DC power for that LED, not 3V AC. So what you could do is use 110V to power an AC to DC wall wart that outputs 3V (or you could use a resistor to alter the DC Voltage of a wall wort with a higher voltage).
The switch I am using, lights up with a LED. The switch is rated to 120v but for some reason, the seller told me the LED is 3V only. I was trying to avoid using a adapter that you plug into the wall if possible
