RESISTORS FOR LED CIRCUITS | RESISTOR APPLICATIONS ...

An LED (Light Emitting Diode) emits light when an electric current passes through it. The simplest circuit to power an LED is a voltage source with a resistor and an LED in series. Such a resistor is often called a ballast resistor. The ballast resistor is used to limit the current through the LED and to prevent excess current that can burn out the LED. If the voltage source is …

LED RESISTOR CALCULATION, AND RESISTOR WATTAGE ...

If you are running an LED from the mains you do not want to run it at 20mA. Any modern LED will be painfully bright at 20mA and your resistor will waste too much power. Try something more like 2mA (though you can use the same calculations, just substitute the current you want) R = E/I = (120-3.4)/0.002 ~= 120/0.002 = 60K, so you can use 62K.
