1k 1 2 Watt Resistor

Guide to the 1K Resistor Color Code

The four band 1K resistor is one of the most common resistors in electronics. Its popularity makes information technology platonic to help larn the resistor color code and it's useful to exist able to readily recognize them in projects.

The 1k resistor color lawmaking allows usa to quickly identify the resistance value and tolerance of a 1k ohm resistor.

In this article, we'll embrace how to read 4 ring, v band, and vi band 1K resistors.

1K Resistor Colour Bands

It's important to realize that not all four bands represent to the amount of resistance in Ohms. The first iii bands tell us that the resistor'southward nominal value is 1000 Ohms, and the quaternary ring gives us the tolerance of the resistor.

Two Helpful Tips for Reading a Resistor:

1) Identify the quaternary ring get-go. This band is virtually always gilded or argent, so it is commonly like shooting fish in a barrel to identify.

2) Await for the gap betwixt the 3rd and 4th band.

2	2nd Digit	Black	0
3	Multiplier	Cherry	x 100
4	Tolerance	Gold (or silver)	± 5%
			Full Value: 1000 ± 5% Ω

How To Read the 1K Resistor Color Code

Resistor colour codes always accept digits, followed past a multiplier, follower by a tolerance value.

For a 4 band resistor, each ring has a specific function:

Band One – 1st Digit: This is the first digit of the resistance value. The showtime band is brownish, which corresponds to the value 1.

Ring Two – second Digit: The 2nd digit of the resistance value. This band is black, which corresponds to the value 0. This is added to the right of the first digit (from band one).

Therefore the digits from band one and band two are: 10.

Band 3 – Multiplier: Takes the digits and multiplies them past a value given past this band. The bodily multiplier is tenⁿ, where due north is the value of the band color. In this case, the third band is red which corresponds to the number ii. Therefore the multiplier is 10ⁱⁱ = 100.

So the total value of the resistance given by the colors is 10 ten 10² Ω = k Ω = 1kΩ.

Ring 4 – Tolerance: Gives the value of the tolerance for the resistor. The most mutual values are 5% (designated past a gold band), and 10% (designated by a silver band). This example uses a golden band, giving u.s.a. a tolerance of 5%.

The full resistance is therefore: 1kΩ ± 5% Ω.

This means that the actual resistance value could be anywhere from 950 Ω to 1050 Ω.

If the fourth band is silver, this means that the tolerance is 10% and the total resistance is 1kΩ ± 10% Ω. The actual resistance should be between 900 Ω and yard Ω.

You tin use a multimeter to find out the actual resistance, but note that information technology volition also vary slightly with temperature.

Multimeters are a great way to check any resistors you aren't sure of, just be sure to follow practical safety guidelines.

4-Band vs. 5-Band vs. 6-Band 1K Resistor Color Code

You lot will probably come across 5 ring or even 6 band resistors on your journeys in electronics.

Luckily, information technology is very easy to read 5 or half-dozen band resistors if you already know how to read a four band resistor.

five Band 1K Resistor Color Lawmaking

For 1K resistors with five bands, the first iii bands will be brown, black, and blackness (indicating 100) and the fourth band will exist brown indicating a multiplier of x10.

Ring Number	Function	Color	Value
i	1st Digit	Brown	ane
2	2nd Digit	Blackness	0
three	3rd Digit	Blackness	0
iv	Multiplier	Brown	ten 10
5	Tolerance	Gold (or silver)	± v%
			Total Value: 1000 ± 5% Ω

	4-Ring Resistor	5-Ring Resistor	6-Band Resistor
1^st ring	ane^st digit of resistance value	1^st digit of resistance value	one^st digit of resistance value
2^nd band	2^nd digit of resistance value	2^nd digit of resistance value	ii^nd digit of resistance value
three^rd band	Multiplier (x 10, 100, etc)	3^rd digit of resistance value	3^rd digit of resistance value
4^th ring	Tolerance (± %)	Multiplier (x x, 100, etc)	Multiplier (10 10, 100, etc)
5^thursday band	N/A	Tolerance (± %)	Tolerance (± %)
6^th band	N/A	Due north/A	Temperature Coefficient R(T)

4 Ring vs. 5 Band 1K Resistor

Four band resistors have ii bands for the value, one for the multiplier, and i for the tolerance. Five band resistors add an actress band for the value.

So five ring resistors have three bands for the value, one for the multiplier, and one for the tolerance. The procedure of analyzing the resistor is the same; start with the 5th band, looking for a small gap betwixt the fourth and fifth band. This volition be the tolerance. Then become dorsum to the first four bands to calculate the resistance value.

6 Ring Resistors

Six ring resistors are exactly similar five ring resistors except they have an extra band to bespeak the temperature coefficient, i.east. how much the resistance will change with temperature.

In this instance, the last ii bands (i.e. the fifth and sixth bands) should be closely spaced, with a gap betwixt the fourth and fifth bands.
