Why Is It Advisable To Use A Fixed Resistor With An Led at Cameron Malone blog

Why Is It Advisable To Use A Fixed Resistor With An Led. A resistor is a poor substitute for a real current. The easy answer is that a 200 ohm resistor is a common. The main reason leds need resistors is to protect the led from excessive current which can permanently damage the led. The best way to drive a led is with a current source rather than a voltage source. So why is a resistor value such as 200 ohms commonly used when the calculations indicate 69 ohms? 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. A current limiting resistor is used in series with a light emitting diode (led). Learn how to use current limiting resistors to ensure stable and safe operation of led devices using constant voltage power sources. A resistor is used with an led to limit the amount of current flowing through it and prevent it from overheating and failing. Leds have current ratings which indicate the. Why is a resistor needed for a led?
