VL = tegangan rangkaian seri LED = jumlah LED dikali tegangan LED/. i = arus LED. Tegangan suplai VT adalah 220 volt. Tegangan rangkaian serie LED adalah 40 x 3 = 120 volt. Arus LED adalah 20 mA = 0,020 A maximal. Maka nilai resistor = (220 - 120) / 0,020 = 5.000 ohm = 5 kilo ohm.

Web29 jan. 2014 · The resistance can be calculated using Ohms Law: LEDs typically require 10 to 20mA, the datasheet for the LED will detail this along with the forward voltage drop. For example an ultra bright blue LED with a 9V battery has a forward voltage of 3.2V and typical current of 20mA. So the resistor needs to be 290 ohms or as close as is available.
