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%
in simple terms, band represent numbers, ex:- 10K resistor have different colour code and that is difference from 5k resistor. if you type in google 'resistor colour code' that will describe how to calculate a resistor value. thanks
As far as I know, nothing. It is the color bands on the resistor that represent the value of the resistor.AnswerIn the, now-obsolete, 'body-tip-spot' colour code system, the 'body' colour represented the first significant figure, the 'tip' colour represented the second significant figure, and the 'spot' colour represented the multiplier. The colours of the 'body-tip-spot' method correspend exactly to the colours used with the 'band' method.With the 'body-tip-spot' method, the body of the resistor was painted in one colour; one end of the resistor (the 'tip') was painted another colour, and a coloured 'spot' or 'dot', was placed roughly halfway along the body of the resistor.
The resistor is identified by a colour code. Most common is the 4 band resistor, band values are as follows - Black- 0, Brown - 1, Red - 2, Orange - 3, Yellow - 4, Green - 5 , Blue - 6, Violet - 7, Grey -8, White 9. The 4 th band is the multiplier.If the picture above is headed "Chicago7" then check the colour bands, they are Blue, 6 green 5 , orange 3, indicating a 65 K ohm resistor.
This question cannot be answered because you did not specify the color of the third band.
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.
The first 3 band on a resistor indicate the value of that resistor.
yep
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.
count up the value of the resistor using the colour bands along with resistor code chart(or it may on the resistor eg. 10kohms, follow this by hooking up an ohm meter(you will have to select ohms, kilo-ohms, mega-ohms whichever applies) , your resistance should appear within the acceptable variable guidelines.. usually 5 to 10 percent(last band or on the resistor itself) count up the value of the resistor using the colour bands along with resistor code chart(or it may on the resistor eg. 10kohms, follow this by hooking up an ohm meter(you will have to select ohms, kilo-ohms, mega-ohms whichever applies) , your resistance should appear within the acceptable variable guidelines.. usually 5 to 10 percent(last band or on the resistor itself)
Resistors are quite small. We use colour codes in order to be able to fit a lot of information in little space. Each colour represent a number. Each band of colour have its own representation. On a 4 band resistor, the first two are actual values, the third is a multiplier and the fourth is accuracy. Please check out related question and answer down below for more information.
