Resistor Color Code with Bands

Did you buy a pack of 500 resistors, only to be mortified to discover how clueless you are about those colorful rings on your new resistors? You wonder, why couldn’t they just print the resistance value on the resistor and make life easier for everyone? If reading resistor color codes sounds foreign to you, then read on!Can you tell which one is the 4.7 kΩ resistor?As resistors are small, it is pretty difficult to print numbers or the resistance value onto the small surface area of the resistor. Thus, instead of directly printing numbers onto the resistor, resistor color codes are used. Resistors can have 3 bands, 4 bands, 5 bands or 6 bands. The colored bands are used to denote the resistance, tolerance and the temperature coefficient.We have put together a simple guide to explain the calculation behind resistor color codes. Reading resistor color codes can become easy once you understand the math behind each colored band.Getting Started: Resistor Color Code ChartBefore getting to the math bit, you have to know about an important tool known as the Resistor Color Code Chart. Similar to how the periodic table is indispensable to a chemist, the Resistor Color Code Chart is your best friend when it comes to decoding a resistor’s code. You will find yourself referring to this chart frequently, as values needed to calculate the resistance value are compiled on this chart. More details on how to use it when we explore examples in the later section!Is there an easy way to remember these colors?Absolutely. If you find it difficult to remember what colors there are in resistor color codes, try these mnemonics.Acronym: BBROYGBVGWPhrase: Bad Beer Rots Our Young Guts But Vodka Goes Well B.B. Roy of Great Britain has a Very Good Wife Bad Boys Race Our Young Girls But Violet Generally WinsGetting Started: Identifying the first colored bandThis is the question that usually arises first because we can’t start calculating the resistance from the resistor color code if we can’t get their reading direction right in the first place. Fortunately, the resistor color code has some visual Clues that give the answer away!The most obvious trick to this is that there is an increased space that occurs before the tolerance band. The bands are not regularly spaced apart and can be seen as being grouped into two. Put the larger group on the left and read the resistor from left to right.The first band is usually always closest to the end. But this may not be the case all the time.If you find a gold or silver color band on your resistor, it is definitely the tolerance band and the last band on the resistor. So, they belong to the right side of the resistor and again, read the resistor from left to right.Also, be sure to check your manufacturer’s documentation to be sure about the resistor color codes used. If none of the ways above are helpful, you can always rely on a multimeter to measure the resistance. Sometimes this might be the only way to figure out the resistance, especially when the color bands are scratched or burnt off.Calculating Resistor Color Codes3 Band Resistor Color CodeFor a 3-band resistor color codes, the first two bands always denote the first two digits of the resistance value while the third band represents the multiplier.AB × C ± 20% 10 × 101 ± 20% = 100 Ω ± 20%Bands:A: 1st band – 1st significant digitB: 2nd band – 2nd significant digitC: 3rd band – multiplierIn the example we have, the bands are brown, black and brown. The first band is the brown band closest to the edge. We look up our resistor color code chart, and find that brown has the 1st significant value of 1 and black has the second significant value of 0. The third band is brown, which means that the multiplier is 1. Using the formula, the resistance is thus calculated to be:As the 3-band resistor has no fourth tolerance band, the default tolerance is taken to be at 20%.The 4-band resistor color code is the most commonly used resistor. Similar to the 3 band resistor, the first two bands always give the first

The wiper moves away from the Reference (R) towards ground (G), the measured signal voltage drops POTENTIOMETER APPLICATIONS • Since potentiometer are used to measure changes in position they naturally are used for throttle, EGR, AC blend door, and power seat position sensors. All potentiometers have three wires and are used to measure position changes RESISTOR RATING COLOR BANDS • The first two bands set the digit or number value of the resistor. • The third band, also known as the multiplier band, is the number of zeros added to the number value. • The last band is the Tolerance band. Example: +/- 10%RESISTOR COLOR BAND CHART • The chart below is used to interpret the color bands on the carbon resistor. Another chart is used to show the value of tolerance band colors READING COLOR BANDS - RATING VALUE • The first color band is Green with a value of "5".The second color band is Red with a value of "2".The third band is Black with a value of "0" zero. (No zeros are added) • So the resistor has a base value of 52 ohms. READING COLOR BANDS - TOLERANCE VALUE • Resistors vary in tolerance (accuracy). Common tolerance values are 20%, 10%, 5%, 2%, or 1%, simply meaning the maximum percent allowable difference the resistor value actually is from the designed value rating. A 1% resistor is a higher quality resistor than one with a 20% rating. • The tolerance band (last band) is silver with a value of 10%. So, the resistance value is "52 ohms plus or minus 5.2 ohms" (46.8 to 57.2 ohms). CAPACITOR • A device used to store charge in an electrical circuit • functions much like a battery but charges and discharges much more efficiently • A basic capacitor is made.

Resistance color code chart, we obtain a tolerance value of ±1% for brown. Beginning from the other end, the first band and second band is yellow and violet, which gives the 1st and 2nd significant digit of 4 and 7 respectively. The extra third band is blue and so the 3rd significant digit is 5. The fourth band is black and gives the multiplier value of 100. Using the formula, we get the resistance value of 475 × 100 = 475 Ω.6 Band Resistor Color CodeA 6 band resistor is essentially a 5 band resistor with an extra ring that denotes the temperature coefficient or sometimes, the failure rate. The most common color for the sixth band is brown (100 ppm/K), which means that for every 10℃ change in temperature, the resistance value changes by 0.1%.ABC × D ± E%, F274 × 100 ± 2%, 250 ppm/K = 274 Ω ± 2%, 250 ppm/KBands:A: 1st band – 1st significant digitB: 2nd band – 2nd significant digitC: 3rd band – 3rd significant digitD: 4th band – multiplierE: 5th band – toleranceF: 6th band – temperature coefficientFor this example, the resistor color code bands can be grouped into 2 groups according to the space between the multiplier band and the tolerance band. Place the larger group on the left and the smaller group on the right and read the resistor from left to right. Again, we check the resistor color code chart for red, violet and yellow, and the first, second and third bands give the significant digits of 2,7 and 4 respectively. The fourth band is black, giving a multiplier value of 100. Hence, we will get a resistance value of 274 × 100 = 274Ω. The fifth tolerance band gives a tolerance value of ±2%. The sixth band is black and gives a temperature coefficient value of 250 ppm/K.Resistor Color Band ExceptionsZero-Ohm ResistorsZero-ohm resistors are resistors that can be easily recognized by their single black band.
