Configuring LED in a series, where do I place the resistor?
If I was going to a configuration of 3 LED lights (10MM), do I need a resistor for each or only for one? And if only for one, how do I calculate for the resistor I need, i.e., does the resistor need to take into account the output of each LED and multiply by 3?
Very new at this, trying to learn as much as I can. All advice is greatly appreciated.

Same current, 3 times the voltage - one resistor.
As you failed to provide the details use them yourself in one of the calculators suggested by Caitlinsdad.

Thank you for the response. I left out the details because at the time of writing I did not have a diagram in mind The calculator search suggested by Caitlinsdad sure were helpful. Thanks again for the quick response. I ended up completing the project last night.

Just search for "LED Calculator" to find an online led circuit designer. Lots of free ones to use. Good luck.
