I just bought an led ring from acex008, but he didn't know what the forward voltage of the leds in it were. Knowing that the supply voltage is 5.0, and there's 10 leds on the ring, if I knew how many ohms the resistor was, I'd be able to tell really easily what the leds' forward voltage is, right? I found something online about color codes (http://www.aikenamps...orColorCode.htm
) and used that with the resistor calculator (http://metku.net/ind...c/index_eng#top
). The resistor calculator said I should be using a 10 ohm 10% resistor (that would be brown-black-black-silver, right?) The one I have is brown-black-brown-gold...which would be 100 ohm 5%, right? Would that be the same thing, or rather, produce the same results?
I'll include a pic, in case I worded this confusingly
Ok, to sum it all up. I'm wiring 10 leds with 3.2 forward voltage in parallel on an led ring. Is this resistor (brown black brown gold) going to work (safely
