How do we calculate them always? Like we can get the reading amp how much consumed say 0.26 amp 12 volt. Now divide to three series each series 4 volt and each series 16 pc parallel chip. Got any easy calculation?

The bulb is 12 volt running dc but as each smd using 3.5 to 4 volt that is why first 16 in parallel and and those three (16 pc parallel each parallel) three in series. If 12 volt condition total 48 pc smd consumed 260 mili each how much forward current?

We are using smd chip led 3528 which prescribe 20 miliamp standard forward current. I want to know basic calculation like those bulb. How do i find forward current? 12 volt dc light, 48 pc smd chip, 16 parallel connection 3 series (as each chip volt is 3.5 to 4) Now we found that 3.14 watt is...
