Does Each Led Need Its Own Resistor at Martin Muller blog

Does Each Led Need Its Own Resistor. One of the first things students are taught about leds is that each led in a parallel circuit must have its own resistor. You don't have to have a resistor to go with your led. We want to balance out having enough current to cause the level of brightness desired without having so much that the led material fails. The parallel connection you are describing will not work. Multiple leds on a single resistor: For higher than 500 ma, we should think about plugging into the wall. A resistor is required to limit the current through each led, except in the case that leds are in series. This instructable will show you how to calculate the required values to connect multiple leds with a single resistor vice an individual resistor per led. You have to have a way to limit the current to the led. If we run four leds in parallel, requiring 100 ma, we should still get pretty decent battery life. From my perspective, the answer is “it depends.” if you’re only switching on a single led at a time, and especially if you’re just prototyping, then you don’t.
