What does the silver and gold bands on a resistor mean?
A gold tolerance band is 5\% tolerance, silver is 10\%, and no band at all would mean a 20\% tolerance.
What are gold and silver Colour coding means in resistors?
The colour code used to denote the tolerance rating of a resistor is given as: Brown = 1\%, Red = 2\%, Gold = 5\%, Silver = 10 \% If resistor has no fourth tolerance band then the default tolerance would be at 20\%.
Why is there a need to indicate the color code values in a resistor when the actual resistance can just be measured using the VOM?
Fixed resistors have different coloured rings or bands around them to indicate their resistive value with each coloured band having a decimal value associated with it. This is because the actual resistive value can have a percentage variation of resistance either side of the nominal value.
What do the colored stripes on resistors mean?
These little stripes of bright colors indicate two important factoids about the resistor: its resistance in ohms and its tolerance, which indicates how close to the indicated resistance value the resistor actually is. The first three stripes indicate the resistance value, and the fourth stripe indicates the tolerance.
How do you read a color band on a resistor?
Always read resistors from left to right. – Resistors never start with a metallic band on the left. If you have a resistor with a gold or silver band on one end, you have a 5\% or 10\% tolerance resistor. Position the resistor with this band on the right side and again read your resistor from left to right.
Why is color coding used for resistors?
Components and wires are coded with colors to identify their value and function. Resistor Color Coding uses colored bands to quickly identify a resistors resistive value and its percentage of tolerance with the physical size of the resistor indicating its wattage rating.
What is Colour coding in safety?
Color coding is a visual reminder system to warn, inform and guide employees. OSHA assigns specific meanings to certain colors; therefore, colors can be a warning of a particular hazard or give information or directions.
When the color gold is used in the multiplier band it means to divide the numeric value of the first two bands by?
Two special cases of the multiplier band (band 3) are used for very small values where gold indicates that the first two bands must be divided by 10, and silver means divide by 100, e.g. 4.7Ω (or 4R7) would be indicated by yellow, violet(47), gold (divided by 10) = 4.7Ω.
Which Colour represents 7 in resistor color code?
Violet
Resistor, capacitor and inductor
| Color | Significant figures | Tolerance |
|---|---|---|
| Yellow | 4 | – |
| Green | 5 | ±0.5\% |
| Blue | 6 | ±0.25\% |
| Violet | 7 | ±0.1\% |
What is Colour coding of resistor?
Resistor Color Coding uses colored bands to quickly identify a resistors resistive value and its percentage of tolerance with the physical size of the resistor indicating its wattage rating. The colors brown, red, green, blue, and violet are used as tolerance codes on 5-band resistors only.
What do the band colours for resistor color code mean?
The band colours for resistor colour code in the order: The tolerance values represent by how much the resistance can vary from its mean value in terms of percentage. A gold band represents the lowest variation, so be sure to buy these at the electronics store. The value of the given resistance is: 22 Ω ± 5\% .
What does a gold tolerance band mean on a resistor?
A gold tolerance band is 5\% tolerance, silver is 10\%, and no band at all would mean a 20\% tolerance. For example: A 220 Ω resistor has a silver tolerance band. 220 Ω stated resistance +/- 22 Ω tolerance means that the resistor could range in actual value from as much as 242 Ω to as little as 198 Ω.
What is the \% of error in a resistor?
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. A gold tolerance band is 5\% tolerance, silver is 10\%, and no band at all would mean a 20\% tolerance. A 220 Ω resistor has a silver tolerance band.
How do you read resistor bands?
1 To read them, hold the resistor such that the tolerance band is on your right. 2 Starting from your left, note down all the colours of the bands and write them down in sequence. 3 Next, use the table given below to see which digits they represent. 4 The band just next to the tolerance band is the multiplier band.
