LED question..

[CrazeD]

What would happen if I had say, a 5v LED and hooked it to a 12v powersource, without a resister? I already know it turns on, it doens't like fry it or anything. Will anything bad happen?

It will burn/melt/fry

Fun stuff eh?

So I take it this is a long term effect? When I put my 5V LED to a 12v power source, it just turns on...lol

 

[the yellow one]

what? LED are very sensitive to high forward voltage but no the other way around. it's going to burn without resistors to take out the excessive current. don't do it man.

Mmm, alright then. That means I gotta go like 20 miles away to get a gay resister, lol.
