The connecting leds a quick reference guide completed with plenty of capabilities that makes it nice product if you would like to grasp more of this location finding tools simply browse its main options below. If your leds are wired in series then one resistor can work as a current limiter for many leds but there are some limits of connecting them in series for example you can not operate 4 leds of 3 volts with 6 volts supply in series because 4 leds of 3 volts are equal to 12 volts so they require 12 volt dc but in parallel you can do that by simply connecting each led with a separate resistor. Guide contents overview what is an led we connect our led through a 1k resistor as we adjust the voltage from 0 volts to infinite volts what happens what happened the led datasheet forward voltage and kvl quick quiz lets say we have the same circuit above except this time its a 5v battery and an led with a forward voltage of . How to connect the leds to understand this lets read the following discussion lets assume you want to design a led display having 90 leds in it with a 12v supply to power this 90 led display to optimally match and configure the 90 led with the 12v supply you will need to connect the leds in series and parallel appropriately
