Thus, for 330-ohm resistor, 1st digit is ‘ 3 ‘, ∴ look for color in a chart with value 3, then it’s your 1st color(say orange). The next 2nd digit is ‘ 3 ‘, ∴ look for color in a chart with value 3, then it’s your 2nd color (say orange).
What color is a 300 ohm resistor?

What is a 330 ohm resistor?
Be the first to review this product. 1/4 Watt, +/- 5% tolerance PTH resistors. Commonly used in breadboards and perf boards, these 330Ohm resistors make excellent LED current limiters and are great for general use. Out of stock.
Why do we use 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.

What resistor do I need for LED 12V?
We’ll use the following formula to determine the resistor value: Resistor = (Battery Voltage – LED voltage) / desired LED current. For a typical white LED that requires 10mA, powered by 12V the values are: (12-3.4)/. 010=860 ohms.
Do you need resistors for LEDs?
Resistors in Light Emitting Diode (LED) Circuits
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 equal to the voltage drop of the LED, no resistor is required.
