Why We Use Resistor In Led at Xavier Longman blog

Why We Use Resistor In Led. The easy answer is that a 200 ohm resistor is a common. A current limiting resistor is used in series with a light emitting diode (led). You have to have a way to limit the current to the led. Learn how to use current limiting resistors to ensure stable and safe operation of led devices using constant voltage power sources. What is needed is a means to limit the current that flows through the led. In this post we will explain why we need this resistor. A resistor is not needed to drive an led. You don't have to have a resistor to go with your led. So why is a resistor value such as 200 ohms commonly used when the calculations indicate 69 ohms? Resistors offer an expedient means for limiting the current. A resistor is used with an led to limit the amount of current flowing through it and prevent it from overheating and failing. Technically, the led and resistor(s) don't use current, because there is no drop in current (the amount of charge passing through.
