What do the colours on resistor mean?
The colored bands on a resistor represent the resistor value and tolerance. The first two bands indicate the significant digits of the resistance value, the third band represents the multiplier, and the fourth band (if present) indicates the tolerance of the resistor. By decoding these colors, you can determine the resistance value of the resistor.
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%
How do you identify carbon resistor using colour code?
To identify the value of a carbon resistor using colour code use the following table...0 - Black1 - Brown2 - Red3 - Orange4 - Yellow5 - Green6 - Blue7 - Violet8 - Grey9 - White... and look at the bands. The first two bands will be the digits, and the third band will be the multiplier. For instance, Brown - Red - Orange will be 12000 ohms, where the 1 is the first band, the 2 is the second band, and the three 0's is the third band.If the third band is Gold or Silver, then the multiplier is 0.1 or 0.01 respectively. For instance, Brown - Red - Gold would be 1.2 ohms, and Brown - Red- Silver would be 0.12 ohms.If there is no fourth band, the resistor is +/- 20%. If the fourth band is Silver, the resistor is +/- 10% and, for Gold, +/- 5%.Some high end resistors have more bands. The 1% resistor will have a third digit band, and some resistors will have a band indicating temperature coefficient.
If you had a 200 ohm resistor with a silver fourth band what would it's maximum value be?
The fourth band indicates the tolerance. Silver is ±10%. Thus, (200 + 0.1*200) = 220 ohms. The minimum, then is (200 - 0.1*200) = 180 ohms. See link.
How do you work out resisters percentage?
On a color coded resistor, there are normally four color bands. The first three represent the value of the resistor and the fourth represents the tolerance of the resistor, i.e. the acceptable variation as a percentage from the stated value. No fourth band allows +/- 20% Silver allows +/- 10% Gold allows +/- 5% Red allows +/- 2% Brown allows +/- 1%
What do the first 3 bands on a resistor indicate?
The first 3 band on a resistor indicate the value of that resistor.
Can you replace a 5 band resistor to a 4 band?
yep
What does the fourth band on a resistor indicate?
It indicates how close the real resistance of the real resistor is guaranteed to be to the numbers indicated by the first three bands. Gold . . . within 5 percent higher or lower Silver . . . within 10 percent higher or lower No 4th band . . . within 20 percent higher or lower
Why does resistance value measured using multimeter differ from one decoded using colour band?
Resistors have tolerance. So does the multimeter. Standard resistors range from 20% (no fourth band), to 10% (fourth band silver), to 5% (fourth band gold). Resistors will not normally measure exactly what you expect, and proper circuit design must take this into account.The multimeter may not be calibrated correctly.
What is color code of 0.27ohms resistor?
The colour code of a 0.27 ohm resistor is red (2) violet (7) silver (0.01) ______123456______Example of a 4 band resistorNote that band 1,2,3 and 5 makes up the 4 in use 27x0.01=0.27 The fourth band (number 5) indicate how accurate this resistor is. In this example, Gold, indicates accuracy within 5% of indicated value. For more information regarding calculation, please have a look at related question below.
What is the 4th colour band on a resistor?
yes
A resistor is marked with the following color bands brown black red and gold What is the resistance of this resistor?
The color bands on a resistor represent the resistor's resistance value. In this case, the colors brown, black, red, and gold correspond to the digits 1, 0, 2, and a multiplier of 10%, respectively. Therefore, the resistance of this resistor can be calculated as 10 * 10^2 ohms, which equals 1000 ohms or 1 kiloohm.
