Why do you need a 330 ohm resistor for an LED?
Detail: 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.
How do I know what resistance band I need?
Buy a Variety of Bands Most bands are color-coded according to tension level (e.g., light, medium, heavy, very heavy). 3 It’s best to have at least three—light, medium, and heavy—since different muscle groups will require different levels of resistance. A favorite for many exercisers are SPRI bands.
How do you identify a 2.2 K ohm resistor?
2.2k Ohm Resistor Color Code The four band 2.2k resistor is very easy to recognize with its’ distinctive pattern of three red color bands. The 5 and 6 band versions have a pattern of red, red, black, brown, followed by the tolerance band and temperature coefficient band on the 6 band version.
What does K mean in ohms?
One kiloohm is equal to 1,000 ohms, which is the resistance between two points of a conductor with one ampere of current at one volt. The kiloohm is a multiple of the ohm, which is the SI derived unit for electrical resistance. In the metric system, “kilo” is the prefix for 103.
What does a 2.2 K resistor look like?
The four band 2.2k resistor is very easy to recognize with its’ distinctive pattern of three red color bands. The 5 and 6 band versions have a pattern of red, red, black, brown, followed by the tolerance band and temperature coefficient band on the 6 band version.
What is the best resistor for LED?
Basics: Picking Resistors for LEDs
|Power Supply Voltage||LED Color||Resistor (rounded)|
|3 V||Red, Yellow, or Yellow-Green||51 Ω|
|4.5 V||Red, Yellow, or Yellow-Green||39 Ω|
|4.5 V||Blue, Green, White, or UV||51 Ω|
|5 V||Blue, Green, White, or UV||68 Ω|
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.
