# How do you find the coded value of a resistor?

## How do you find the coded value of a resistor?

To calculate the resistance value, you need to group the values of the significant digits bands — i.e., the values of the first two or three bands from the left, depending on the total number of bands. Then you need to multiply that value by the multiplier to get the resistance value of the resistor.

## How do you read a 3 band resistor?

For a 3-band resistor color codes, the first two bands always denote the first two digits of the resistance value while the third band represents the multiplier. In the example we have, the bands are brown, black and brown. The first band is the brown band closest to the edge.

What is the value of the third band of a 4 band resistor?

4 band resistor By using the color code chart, one finds that green stands for 5 and blue for 6. The third band is the multiplier, with red representing a multiplier value of 2 (102). Therefore, the value of this resistor is 56 · 102 = 56 · 100 = 5600 Ω. The gold band means that the resistor has a tolerance of 5%.

How to calculate resistor value?

B = 0.1%

• C = 0.25%
• D = 0.5%
• F = 1%
• G = 2%
• J = 5%
• K = 10%
• M = 20%
• ### How to decode a resistor?

Decide which band is the first band.

• Look up the color of the first band in the column labeled “1st digit” and find the number associated with that color.
• Look up the color of the second band in the column labeled “2nd digit” and find the number associated with that color.
• ### How to check a resistor?

– Black = 1 – Brown = 10 – Red = 100 – Orange = 1000 (or 1 K) – Yellow = 10,000 (or 10 K) – Green = 100,000 (or 100 K) – Blue = 1,000,000 (or 1 M)

What is a resistor code?

Standard SMD resistors are marked with a three-digit code, in which the first two digits represent the first two numbers of the resistance value with the third digit being the multiplier, either x1, x10, x100 etc.
