Identifying resistors by color bands
WebResistor color coding is a system of identifying resistor values based on the color of bands painted across the component. This system allows electricians and other electrical professionals to quickly identify the value of a resistor without having to use a calculator or reference guide. Web17 sep. 2013 · Figure 2.1: 4- band resistor In case of five color bands first three bands are the significant figures of the value, the fourth band is a multiplier and fifth band is the tolerance band. Figure 2.2: 5-band resistor 2. Electric Circuit Analysis – I Page 2 of 7 In case of six color bands the sixth band is the temperature coefficient band.

Did you know?
WebThe most popular code is a four-band system. There are two resistance bands, one amplifier, and one tolerance band on these resistors. These bands are gray, blue, red, and gold. Applying the color code table, one can see that green represents 5 and blue represents 6. As a result, the meaning is 56100 = 5600. WebCalculating a 3-band resistor color code is relatively simple and straightforward. To calculate the resistance value, you need to use the formula R = (first two colors) x (third color): R = (1st Color x 10) + (2nd Color) x (3rd Color) For example, if you have a resistor labeled brown, black, and red, it would read as 1×10+0x100 which equals ...

Web26 mrt. 2016 · There are two main types of resistors: Standard resistors have four color bands. Three of the bands tell you the nominal value, which means the value the resistor was designed to have.The fourth band tells you the tolerance of the resistor, which indicates how far off the nominal value the actual resistance could be. (The …
Web4 jan. 2024 · The first two bands represent the significant digits, the 3rd is the multiplication factor, the 4th is the tolerance, and the 5th is the temperature coefficient (ppm/˚C). The third band is the multiplier so it is just grey = 8 , red = 2 , multiplier silver = 0.01 , Tolerance gold = 5% and the temperature coefficient green = 20. So it is 0.82 Ohms. is japan the land of the rising sunWeb5 apr. 2024 · Figure 2: A common zero ohm resistor identified by a single black band. Color blindness.
