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.
The tolerance band identifies how close to the nominal value the resistor is expected to be. No band means +/- 20%, silver band means +/- 10%, and gold band means +/- 5%.
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%.
It's the tolerance of the resistor - +/- 10% (grey), 5% (tan/orange), 2% (red), 1% (dark red/maroon), etc.
47000 ohms with a 10% tolerance Yellow = 4 Violet = 7 Orange = 1000 (this is the multiplier) Silver = 10% tolerance
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.
yep

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.
On a standard four band resistor: yellow, violet, black, and gold.
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%
It's the tolerance of the resistor - +/- 10% (grey), 5% (tan/orange), 2% (red), 1% (dark red/maroon), etc.
47000 ohms with a 10% tolerance Yellow = 4 Violet = 7 Orange = 1000 (this is the multiplier) Silver = 10% tolerance
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.
The first band, brown, indicates the digit 1.The second band, red, indicates the digit 2.The third band indicates the multiplier. For yellow, this is 10000.12x10000 = 120,000 ohms.The last band is an indication of the tolerance of the resistor; gold means the actual value is within 5% of the stated value.
First off, it's going to have a brown and an orange ring for the first two bands but then your last band is going to depend on the tolerance of the resistor whether it's +/- %.05 up to +/- %10.
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%
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.
If there is no fourth band (the tolerance band) then the component's tolerance value is 20%.
