Configuring LED in a series, where do I place the resistor? Answered
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.
