LED Question
I ordered 3 3 volt LEDs and I want to connect them to a 9 volt battery. Is it possible to do this just by hooking them in series? (Positive to negative.) Would I need a resistor?

Re: LED Question
Also I am not sure if it is possible. Ideally I would like to connect six to one 9volt battery. Is there a way to connect six three volt LED's to a 9 volt battery?
Here is the type I am using.

Re: LED Question
Kind of?
My expertise goes as far as this reference page that I just found:

Re: LED Question
It seems like it could be possible, but I am not sure of the wiring and resistor value.

Re: LED Question
I think if you only only want 6 LEDs and a 9V battery...
you would follow the process of this diagram for the forward voltage of your LEDs, your target current, and either 3 lines of 2 LEDs or 2 lines of 3 LEDs.
I also think 3 LEDs in series for one 9V battery (without any resistors) would be fine, but the battery will drain faster.

Re: LED Question
So if I run two lines of 3 each (9 volts each line) the one battery can handle it? I was worried that each line would be trying to pull 9 volts at the same time and the one battery wouldn't handle it well.

Re: LED Question
Sounds like I can run those two lines of three 3 watt led's each with a resistor. I ordered some 1/4 watt 1ohm resistors. I hope those will work. I am no electrical expert.
