Hi guys,
This is a real simple question, can someone just double check my workings for a LED project I'm working on;
Basically I have a panel that consits of 35 LEDs - all the same type.
I have wired them in parallel running off a single resistor (I know not ideal but I'm really tight on space)
So the Source Voltage is 12v
The LEDs have a votage range of 2~2.2v (I'm using 2v for this project to give me some headroom) & a Max Forward Current of 20ma so my math is:
R = (12 - 2) / 0.7
R = 14.285
So this would mean I'd need a 10w 15ohm resistor?
Thanks guys!
