The voltage drop across an LED is about 2 V for red and green, and about 4 V for blue. circle-frequency filter and its application

"WebResistance is measured in ohms, often written as the symbol Ω. The bigger the resistance value (in ohms) the more it fights. Most resistors you'll see range between 1 ohm and 1 megaohm (1.0 MΩ). Since the resistive element is inside a ceramic casing, its not possible to tell the resistance of a resistor just by looking at it. " - Green led resistance
