How Many Volts For Led at Lily Johnson blog

How Many Volts For Led. This means, that you can run all 3 red leds without any resistor, if. In one configuration, the source voltage must be greater than or equal to the sum of the individual led voltages; It depends on the led but between 1.8 and 3.5v. Red leds have the lowest voltage, yellow and green are a little higher. The led voltage v l is determined by the colour of the led. Typically the led voltages add up. There is 5v from a pin so you need a resistor as well as an led to limit the current. Blue and white leds have the highest voltages. You basically fried the led because you did not limit the current to the led. A typical led needs 20ma of current. So if you have a 5v power supply and each of your leds have a forward voltage drop of 2.4v then you can't power more than two at a time. Let say a normal 5mm red led. This led calculator will help you calculate the resistor values you will need when designing a series/parallel led array circuit. The typical forward voltage of leds are 1.8v (red), 2.0v (yellow), 2.2v (green) and about 3v to 3.5v for blue.
