Feb 11, 2019· Rule number 2 from the series circuit bullet points proves that 12V dc isn’t enough voltage to run all 9 LEDs in-series (9 x 2.98= 26.82V dc). However, 12V dc is enough to run three in-series (3 x 2.98= 8.94V dc). And, from the parallel circuit rule number 3 we know that total current output gets divided by the number of parallel strings.
