Resistor

Posted in Personal/Blogging Stuff by mandodong on March 8, 2010

What is the ability of a resistor? Actually, the resistor are the most commonly used device in electronic components. It is a device that limits or resists current. Its resistance is measured in  “ohms”. It is represented by the Greek symbol Omega.

Most of the resistors have “fixed” values, but some have controlled resistance. It is measured in VOM or by color coding or in abbreviations.In color coding of a four band resistor, the first two colors are the first and the second digit, the third is its multiplier and the 4th is its Tolerance.

In five band resistors, The first three colors are the first, second and the third digit. The 4th is its multiplier and the 5th is its tolerance. The resistor color values are :

COLOR                  DIGIT                     MULTIPLIER                        TOLERANCE

Black                      0                              100

Brown                   1                              101

Red                         2                              102

Orange                  3                             103

Yellow                   4                              104

Green                    5                               105

Blue                       6                              106

Violet                    7                              107

Gray                     8                              108

White                   9                              109

Gold                                                       0.1                                             +- 5%

Silver                                                   0.01                                           +- 10%

None                                                                                                        +- 20%

The different varieties of resistors are Precision  Wire-wound , Power Wire-wound, Carbon composition, Foil, Fuse resistor, Carbon film, Metal film, Filament Wound, and Power File Resistor, Different resistor have different use and purpose.
