Why Do You Need A Resistor With An Led at Richard Sandoval blog

Why Do You Need A Resistor With An Led. The main reason leds need resistors is to protect the led from excessive current which can permanently damage the led. So why is a resistor value such as 200 ohms commonly used when the calculations indicate 69 ohms? Why is a resistor even needed, and how would you know what ohms it should be? As usual, alex at tinkerlog does an excellent job of clearly describing some electronics arcana, in this case, exactly why one needs to use current limiting resistors on leds (and when you can do without them). A current limiting resistor is used in series with a light emitting diode (led). The answer from stevenvh explains what you need to do, but you also must calculate the power dissipation across the led. For low current leds that need to be precisely controlled for brightness, you would use a constant current source rather than a. In this post we will explain why we need this resistor. Leds have current ratings which indicate the. The easy answer is that a. A resistor is not needed. The parameter of primary importance is the.
