Do You Need A Resistor For Led. A resistor is not needed to drive an led. Choosing the right resistor is will ensure an led receives proper voltage and current. However, if you are using a 5 v supply voltage,. Resistors offer an expedient means for limiting the current. You have to have a way to limit the current to the led. You need to find a datasheet for your leds or measure their forward voltage so that you can work out what resistance you need to avoid burning them out. What is needed is a means to limit the current that flows through the led. You don't have to have a resistor to go with your led. Let's explore how to calculate the right. If you are building an led system. 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 blue led has a typical forward voltage drop of 3.2 v, therefore a 5 ω resistor is required when using a 3.3 v supply voltage.
