Likewise, what is a 330 ohm resistor?
330 ohms may be used by some people as a "get you going" value that works "well enough" in many cases. The purpose of the resistor is to "drop" voltage that is not required to operate the LED, when the LED is operating at the desired current.

Why is resistor needed with LED?
Resistors in Light Emitting Diode (LED) Circuits An LED (Light Emitting Diode) emits light when an electric current passes through it. The ballast resistor is used to limit the current through the LED and to prevent that it burns. If the voltage source is equal to the voltage drop of the LED, no resistor is required.What color is a 220 ohm resistor?
