Resistor help

[buickgnx]

can i use a 100 ohm instead of 82 ohm ?

Would help if you told us what you where doing with it...

.im going to use 8 blue smd's on a gameboy color.

Its ok, but the leds will be a little dimmer.

thank you

actually it will be a little brighter, the lower the resistance the brighter the led.  OHMs law: Voltage = Current(I) x Resistance..... V = I * R  If voltage remains constant(and it does..pretty much) when (R) is decreased (I) must increases and vise versa

and he's going to increase the resistance...  100Ω vs 82Ω

haha, I is good at reading! I tend to mix things up in my head a lot.  Darkshot was right it will make the led dimmer, however my explaination is still correct
