What does black mean on a resistor?
Resistor tolerance
| Color | Tolerance |
|---|---|
| Yellow | 4% |
| Gold | 5% |
| Silver | 10% |
| Black | 20% |
What does the last band on a resistor mean?
tolerance
The first few bands always represent digits in the value of resistance. Then you will find a multiplier band to signify moving the decimal right or left. The last bands represent tolerance and the temperature coefficient.
What is the tolerance of black in resistor?
The Resistor Colour Code Table
| Colour | Digit | Tolerance |
|---|---|---|
| Black | 0 | |
| Brown | 1 | ± 1% |
| Red | 2 | ± 2% |
| Orange | 3 |
Which digit is represented by a GREY band on a resistor?
Digit, Multiplier, and Tolerance Band Chart
| Color Name | Digit band | Multiplier band |

| Green | 5 | 100,000 |
| Blue | 6 | 1,000,000 |
| Violet | 7 | 10,000,000 |
| Gray | 8 | 100,000,000 |
What does the Fourth Colour band on a resistor mean?
resistor’s tolerance
The fourth color band indicates the resistor’s tolerance. Tolerance is the percentage of error in the resistor’s resistance, or how much more or less you can expect a resistor’s actual measured resistance to be from its stated resistance.
What is the tolerance of black?
What does the first band on a resistor look like?
The first band looks 100% black. It’s reading a consistent 148 Ω, but the left lead heated up and separated from the board. As I read it, it’s black, Black or Brown, Orange, Gold. Damaged resistors (as I understand it) usually increase in resistance (though can short [usually high value resistors]).
Which is the black band on a zero ohm resistor?
(The first band is almost never black, except in the unusual case of a “zero-ohm” resistor: a single black band, otherwise known as a “wire.”) The third band is the multiplier band; red signifies multiplication by 100, making the total value 10 x 100 = 1,000 ohms — or “1k.” The 4th band is the tolerance band;
What does the third stripe on a resistor mean?
The third stripe is brown. Since brown is 1, it means add one zero to the right of the first two digits. Yellow-Violet-Brown = 4-7-0 = 470 Ω. Although the first two bands are fairly straightforward, the third and fourth bands might require a bit more explanation.
What does the color code on a resistor mean?
Resistor Color Codes. Each one has a value that tells how strongly it resists current flow. This value’s unit is the ohm, often noted with the Greek letter omega: Ω. The colored bands on a resistor can tell you everything you need to know about its value and tolerance, as long as you understand how to read them.
