WebSep 1, 2024 · We already know that a LED requires a particular forward voltage (FV) to get lit. For example a red LED will need a FV of 1.2 V, a green Led will require 1.6 V and for a yellow LED it is around 2 V. The modern LEDs are all specified with approximately 3.3V forward voltage irrespective of their colors. WebThe more energy that is put into the bulb, the harder it is for the current to flow – the resistance of the bulb increases. As the voltage increases, so does the temperature of the thin wire ... WebLets start with the series part of the circuit. Lets say we want to run a total of 9 Cree XP-L LEDs at 700mA each with a voltage of 12V dc; the forward voltage of each LED at 700mA is 2.98V dc. 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). look down her nose
