A: It just tell you the resistor has a +- % tolerance in its value. Like a 1000 ohms +-5% it can be off + or - that much.
That has being the standard for forever however that band is disappearing since most resistors are made +-5% as a rule.

What is the value of a resistor with brown black red and silver?
That would be a 200 Ohm resistor, and you didn't mention the tolerance, so I'm guessing you didn't see another band which means the tolerance would be at 20%
Tolerance of a resistor marked 2K2M?
20%
What is the resistor E12 series?
10% tolerance.
How can you find a resistance of resistor without DMM explain the method with the help of example?
Hi You can find the value of the resistor by using colour code printed on the resistor. 1. Hold the resistor such that the colour code starts from left. 2. Each of the colour bands present on the resistor specifies a value. 3. The first colour band represents the first significant figure, the second band represents the second significant figure and the third band indicates the multiplier. The fourth band represents the tolerance. Gold band- 5%, Silver band-10%, No band-20% 4.Find the appropriate values for the colour by using the chart 1. 5. Find the value of the resistor by using the formula 1. Chart1 Example: Here first band represent brown. Second band represent black. Third band represent red . Fourth band represent gold. The value of resistor = 10 x 102 ± 5% = 1kΩ ± 5%
What is the Effect of tolerance on power of the resistor?
The tolerance of a resistor is basically a measure of how close the actual resistance of that particular resistor is to the stated resistance. For example, a "220 ohm" resistor with a tolerance of 10% (silver band) has an actual resistance somewhere between 198 and 242 ohms.
A resistor is marked with the following color bands brown black red and gold What is the resistance of this resistor?
1000 ohms = 1Kohm; silver is the tolerance band of the resistor. Silver signifies plus or minus 10%. The fourth band is always the tolerance band. If there is no tolerance band, the tolerance is plus or minus 20%. A gold band would signify plus or minus 5%.
What is the function of the tolerance band on a fixed resistor?
A: Not all application need close tolerance of values some application only need 5% and some 10% so the band is there to specify the -/+ % tolerance that the part is in compliance with. Designers decide what parts % is needed for proper performance of the circuit.
What are the color codes on a 47 Ohm resistor with a tolerance of 5 percent?
On a standard four band resistor: yellow, violet, black, and gold.
What is the value of a resistor with brown black red and silver?
That would be a 200 Ohm resistor, and you didn't mention the tolerance, so I'm guessing you didn't see another band which means the tolerance would be at 20%
What is the concept of resistor tolerance and its importance?
Resistor tolerance is how accurate the resistor value is. You may have a 10% tolerance, 820 ohm resistor, which means the actual value of resistance is 820 ohms +/- 82 ohms. If you design a circuit that has very stringent requirements for resistor values, you may need to purchase a resistor that has a smaller tolerance (like 5, 2, 1, .5%). The smaller the tolerance, the more expensive it will be (generally).
What doe the last color band on a resistor represent?
It's the tolerance of the resistor - +/- 10% (grey), 5% (tan/orange), 2% (red), 1% (dark red/maroon), etc.
How do you get minimum and maximum value of resistor?
The minimum and maximum possible value is defined by the tolerance. To calculate the range of the resistor, simply add or remove the amount of the tolerance. For example, a 100Kohm resistor with 5% tolerance can range from 95Kohm through until 105Kohm. The lower the tolerance, the more accurate the resistor is.
How is resistor tolerance expressed?
Percent
What is the value of a 4-band resistor with yellow violet orange and silver as the bands?
47000 ohms with a 10% tolerance Yellow = 4 Violet = 7 Orange = 1000 (this is the multiplier) Silver = 10% tolerance
What is the value of a resistor with red red brown silver?
220 ohms with a 10 percent tolerance. Red is 2 and brown is 1. Brown is in the multiplier band so it is 10 times the value in the first two bands. Silver is in the tolerance band. Gold would have been a %5 tolerance device.
Tolerance of a resistor marked 2K2M?
20%
What is the resistor E12 series?
10% tolerance.
