Resistor color code
Four colored rings are used to indicate the resistance value at a fixed resistor. These rings are placed close together at one end of the resistor body. Color of each ring defines a number. See the figure bellow
This color code read from the end nearest resistor, we can know that these colors have meaning:
- The first ring, the first digit of the value of resistance
- The second ring, the second digit of the value of resistance
- The third ring, a multiplier factor (a rank value of 10, or the number of zeros behind the first two digits)
- The fourth ring, is the tolerance of the value of resistance
The table below shows the meaning of the colors on the resistor body

Thanks sob...kunjungan balik saja euy
ReplyDeleteBerkunjung... wah jadi ingat pelajaran SMA-ku .. HICOMEOKUHIBI... menghapal warna-nya... Sukses Selalu..!!
ReplyDeleteThis is a very clear and easy to follow description about what the color codes on resistors mean. I am going to hold onto this for future reference.
