How to Calculate 5 Band Resistor Color Code? A Step-By-Step Guide

Are you struggling to determine the resistance value of a 5-band resistor? Don’t worry, you’re not alone. Many people find it challenging to decode the color bands on resistors and calculate their values accurately. However, understanding how to calculate 5 band resistor color code is critical if you want to design circuits or troubleshoot electronics effectively. In this article, we’ll provide you with a step-by-step guide on how to decode the color bands on a 5-band resistor and calculate its resistance value quickly and accurately.

Now, let’s dive into the detailed article:

How to Calculate 5 Band Resistor Color Code? Step-By-Step

Resistors are essential components in electronic devices that limit the flow of electric current. They come in different sizes, shapes, and colors. One of the most common types of resistors is a 5-band resistor. These resistors have five colored bands that indicate their resistance value, tolerance level, and temperature coefficient.

To calculate the resistance value of a 5-band resistor accurately, you need to follow these steps:

Step 1: Identify the Color Bands

The first step is to identify all five color bands on your resistor. The first three bands represent significant digits of the resistance value in ohms (Ω), while the fourth band represents the multiplier or number of zeros that should be added after those digits.

The fifth band indicates either tolerance or reliability rating, which is expressed as a percentage or letter code.

Here’s what each color band represents:

  • Black: 0
  • Brown: 1
  • Red: 2
  • Orange: 3
  • Yellow: 4
  • Green: 5
  • Blue: 6
  • Violet/Purple: 7
  • Gray: 8
  • White:9

Gold and Silver are used for multipliers and tolerances.

Step 2: Determine the Resistance Value

Once you’ve identified all five color bands on your resistor, you can determine its resistance value by using this formula:

Resistance = (Digit1 *10 + Digit2) * Multiplier

For example: Suppose your resistor has these colors: Brown | Black | Red | Gold | Brown

Then, Digit1 = Brown =1 Digit2 = Black=0 Multiplier = Red=100 Tolerance= Gold=±5%

Using our formula: Resistance=(1*10+0)100Ω ±(0.05200)=100Ω±10%

Therefore, your resistor has a resistance value of approximately 100 Ω with a tolerance level of ±5%.
