I am wanting to connect 4 LED's together to a 12 volt power source....well
to be specific...my car.
I know that they are 1.7 volt and 20ma per LED and I need to use a 1/4 watt
270 Ohms resistor.
My question(s) is this:
I think that I should be connecting the resistor to the incoming positive
side voltage source but I don't know if I connect all the LED in parallel
(all positives and negatives together) or series (positive to negative and
so on) or if an LED has a negative/ positive side.
I know this must be elementary but I"m just leaning.
Thanks for your help.
