5 band resistor colour code

table of resistor coulor code table

Carbon resistors are most common in electronic equipment. They consist of a high-grade ceramic rod or cone ( called the substrate on which is deposited a thin resistive film of carbon.
The numerical value of their resistance is indicated by a color code which consists of bands of different colors printed on the body of the resistor. The color used in this code and the digits represented by them are given in the table below:
Usually, the code consists of four bands. Starting from left to right.

How to read 5 band resistor color code

The 5 band resistor color bands are interpreted as follows:

  1. The first band indicates the first digit in the numerical value of the resistance.
  2. The second band gives the second digit.
  3. The third band is decimal multiplier i.e, it gives the number of zeroes after the first two digits.
  4. The fourth band gives resistance tolerance. Its color is either silver or gold. The silver band indicates a tolerance of ± 10 %, a gold band shows a tolerance of  ±5 %. If there is no fourth band, tolerance is understood to be ± 20%. By tolerance, means the possible variation from the market value. For example, a 1000 Ω resistor with a tolerance of ± 10 % will have an actual resistance anywhere between 900 Ω and 1100 Ω.

How to calculate Five Band resistor Color Code?

Certain precision resistors with a tolerance of 2 %, 1 %, or less are generally color-coded with five bands  as shown in the figure given below:

The first band is the first digit of the resistance value, the second band is the second digit, the third band is the third digit, the fourth band is a multiplier ( number of zeroes after the third digit), and the fifth indicates the percent tolerance.
