WebGLOBAL LED RESISTOR MARKET . INTRODUCTION. When an electric current flows through an LED (Light Emitting Diode), the LED begins to produce light. A voltage source connected in series with a resistor and an LED is the simplest arrangement for powering an LED.A ballast resistor is a common name for this type of resistor. WebExample 1: 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. However, if you are using a 5 V supply voltage, then a 90 Ω resistor is needed. As you can see, the resistor value increases as the supply voltage increases.
