The tolerance for three bands resistor is generally ±20% i. If you feel difficult to find the resistance of the resistor by using its color bands, you can directly find the resistance by using ohmmeter or multimeter. Color Value Black 2nd and 3rd bands only 0 Brown 1 Red 2 Orange 3 Yellow 4 Green 5 Blue 6 Violet 7 Grey 8 White 9 Mnemonics were created to easily memorize the sequence of the colors. How to read resistor color code? In the similar way, in resistors we use different colors as codes to specify the resistance information of the resistor. Here, the different colors coated on the resistor act as codes. Here, two colors are added gold and silver.
You should always attempt to work out the value, then check your result against a resistor value chart to see if it's listed there. The first 2 digits make the number 43. Just have a look to the resistor color code chart below and see the calculations, how the resistance value is calculated according to this chart. The 3 color bands on the left side are grouped together to indicate the resistors resistance value and the 4 th color band on the right side indicates the tolerance of the resistor. To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code calculator.
Four band resistors typically use this reliability band. We can also directly find the resistance value of a resistor by using ohmmeter. For blind people, it is impossible to find the resistance of the resistor, because they cannot see the colors coated on the resistor. The fourth band is usually silver or golden in color. In the color code table, brown has a value of 1 which is the 1 st digit, green has a value of 5 which is the second digit and red has a value of 2 which is the 3 rd digit.
Therefore, the resistor color coded with brown-green-red-violet would have a resistance of 1500 ohms with a tolerance of ± 0. To know the value of a resistance, use an ohm-meter or read the color code on the resistor. Example: If the colors on a 6 band resistor is in this order: green, brown, violet, black, gold and orange. A 10 V source connects to the circuit. Each color on the resistors body represents a different number.
Repeat for all bands tolerance is optional. Next comes a small gap - helping you to distinguish left and right of the component - and finally the fourth band indicating tolerance of the resistor. In a 6 band color code the, what does the 6th band represent? Example: A resistor of 220 ohms Ω with a tolerance of 10%. The corresponding digits are 5 and 2. If the 4 th color band or tolerance band is left blank, it is considered as the 3 band resistor and the tolerance for the 3 band resistor is assumed to be 20%. In present case the current through circuit is too lower.
The resistors of high tolerance have high variation in the resistance. Preferred resistor values: Converting a value either way will display the nearest preferred resistor value below the image of the resistor. Our color code calculator runs this check automatically for you, and if the result is not a standard value, it will display a small tip. The color codes are also used to specify the tolerance and reliability of the resistor. Again, read the resistor from left to right. Resistor Colour Code Calculator This calculator converts resistor values to or from 5-band or 4-band colour codes. If you want to find out the color bands for a value, use the tool on the left.
For example, a resistor that has a tolerance of 5% may vary 5% of its resistance from its actual resistance value. The values of resistance and the wattage rating of large power resistors are imprinted on their bodies. The 1 st, 2 nd and 3 rd color bands together make up a 3 digit number and the 4 th color band or multiplier is multiplied with this 3 digit number to obtain the resistance value of the resistor. Violet specifies that the tolerance is 0. The first question which usually arises is: how do I know from which end should I start reading my resistor color code? As we know that resistor is a basic component and we can find it in any electronic circuit.
To read the five strip colors codes on a resistor, the first, second and third strip color codes shows the first significant, second significant and fourth significant figures accordingly. What happens, if I start reading from the wrong end? What is the color code of 333kΩ,± 5% five band resistor? Resistor Color Code Calculator Use this website to convert resistor color codes into resistor ohm value and tolerance. Example on how to use this resistor color code calculator We've tried really hard to make the resistor color code calculator as simple and intuitive as possible, but if you have any problems, just have a look at the example below! The second strip shows the second significant figure and the third strip shows the multiplier. Resistors that are manufactured for military use may also include an extra band called 5 th band which indicates resistor failure rate. There is a special scenario in case of 5 band resistor color code resistor where the forth strip is Goldor Silver. The decoding changes based upon the number of color bands painted on the resistors body.
There's a lot of options, depending on tolerance and number of bands. The fourth band or 5th for the 5-band and 6-band indicates the tolerance values. The warnings are there for your information only and do not always imply that the resistor is was read the wrong way -- see the notes below. The resistors with high resistance value will restricts large amount of electric current whereas the resistors with low resistance value will restricts only a small amount of electric current. Use the radio buttons below the image to select the series of preferred values to use E12 - E192. A 6-band resistor is like a 5-band but includes a temperature coefficient band.
Generally, there's a gap before the tolerance band, so that's how you can recognize start and end. Fortunately, couple visual hints exist! To read the six strip colors codes on a resistor, the first, second and third strip color codes shows the first significant, second significant and third significant figures respectively. Every color is a different number: color name digit color color name digit color black 0 green 5 brown 1 blue 6 red 2 violet 7 orange 3 gray 8 yellow 4 white 9 It's the color code working for the first 2 or 3 bands from the left side. The forth band in 4 band resistor color is used for tolerance value. In this case, the first two bands shows the fist two significant digits, third one is for multiplier, 4th one is for tolerance and 5th one is for temperature coefficient same is in six band resistor color code resistor.
