Why Use A Resistor With An Led at Mireille Beth blog

Why Use A Resistor With An Led. We've put together this guide to help anyone from the novice diy guy to those designing and building led lighting circuitboards fully understand. The main reason leds need resistors is to protect the led from excessive current which can permanently damage the led. An led (light emitting diode) emits light when an electric current passes through it. Leds have current ratings which indicate the. A resistor is used with an led to limit the amount of current flowing through it. So why is a resistor value such as 200 ohms commonly used when the calculations indicate 69 ohms? An led behaves very differently to a resistor in circuit. The simplest circuit to power an led is a voltage. Limiting current into an led is very important. 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. Resistors in light emitting diode (led) circuits. The easy answer is that a 200 ohm resistor is a common. If you have a high current led or a very large voltage difference, then the resistor has to waste a lot of power.
