As we know a 4 Band Resistor is a type of Fixed Resistor in through hole package with two terminals, these are commonly used in electronic circuits to limit the current and drop the voltage level. These four band Resistor indicates its value through four different colors and their positions. 4 Color Band Resistor will have priority to calculate its value as First Band (First Numerical Digit), Second Band (Second Numerical Digit), Third Band (Multiplier) and Fourth Band (Tolerance).

To start decoding the Color of 4 band Resistor we need to identify the First or Last (Tolerance) Band, Most of these component comes with Gold or Silver Color Tolerance band that is last Band. So we need to position it to the right hand. Here the last tolerance band in right hand side. Now starting with the first color from left hand side. As previously said First Band color numerical value and Second band Color numerical value should be written down as it is. Then third band is multiplier ( 10^{color number }), Multiply the written numbers (First, Second digit) with the corresponding multiplier. Now we get the Resistor Value then final Last band is Tolerance band ± in percentage. Finally we get the Value of 4 band Resistor.

Color and Value | First Band | Second Band | Multiplier | Tolerance |
---|---|---|---|---|

Black (0) | 0 | 0 | 1 Ω | |

Brown (1) | 1 | 1 | 10 Ω | ±1% |

Red (2) | 2 | 2 | 100 Ω | ±2% |

Orange (3) | 3 | 3 | 1 kΩ | |

Yellow (4) | 4 | 4 | 10 kΩ | |

Green (5) | 5 | 5 | 100 kΩ | ±0.5% |

Blue (6) | 6 | 6 | 1 MΩ | ±0.25% |

Violet (7) | 7 | 7 | 10 MΩ | ±0.10% |

Gray (8) | 8 | 8 | 100 MΩ | ±0.05% |

White (9) | 9 | 9 | 1 GΩ | |

Gold (±5%) | 0.1Ω | ±5% | ||

Silver (±10%) | 0.01Ω | ±10% |

From old school method for remembering the Resistor color code, here is the simple and funny mnemonics “**BB** **ROY** **G**reat **B**ritain **V**ery **G**ood **W**ife **G**old **S**ilver” here the color code goes as **B**lack, **B**rown, **R**ed, **O**range, **Y**ellow, **G**reen, **B**lue, **V**iolet, **G**ray, **W**hite, Gold and Silver. So the Numeric and Multiplier Number (x10^{color}) starts from 0 to 9.

Consider you are holding a four band Resistor with color code as Red, Red, Brown and Gold.

First Band Red = 2, Second Band Red = 2, Third Band Multiplier = 1 = *10^{1}, Fourth Band Tolerance = ±5%.

22*10^1=220 Ω Ohms with ±5% Tolerance, which means your Resistor will have Resistance value between 231 Ω to 209 Ω.

Understanding resistor values is fundamental for anybody working with gadgets. The 4-band resistor variety code is one of the most well-known designs for recognizing resistor values.

Precision is basic while working with resistors in electronic circuits. Our number cruncher gives exact computations, giving you the right obstruction esteem in ohms (Ω) alongside the resistance.

The outcomes are shown plainly, showing the obstruction worth and resistance. This permits you to rapidly reference the data while building or investigating circuits.

**Select the Band Colors:**Pick the varieties for every one of the four groups. The initial two groups address the critical digits, the third band is the multiplier, and the fourth band is the tolerance.**View the Resistor Value:**The mini-computer will right away show the resistor's worth in ohms and demonstrate the resilience percentage.**Example:**

Assuming your resistor has variety groups of Red, Violet, Yellow, and Gold:

- First Band (Red) = 2

- Second Band (Violet) = 7

- Multiplier (Yellow) = 10,000

- Resistance (Gold) = ±5%

- Result: 270,000 ohms or 270kω with a ±5% tolerance.
