How to Quickly Read the Color Code of a ResistorResistors use colored bands to show their value. Let’s break it down step by step with an example:Example resistor: Brown – Red – Red – GoldStep 1: Read the first two colors (the base number)Brown = 1Red = 2So, the base number is 12.Step 2: Look at the third color (the multiplier)Red = 2 zerosSo, we add two zeros to 12 → 1,200 Ω.Step 3: Check the fourth color (tolerance)Gold = ±5%This means the resistor’s actual value can vary by 5%.So, the resistor value is:1,200 Ω (1.2 kΩ) ±5%Step 4: Understand what tolerance means±5% of 1,200 Ω = 60 ΩMinimum value: 1,140 ΩMaximum value: 1,260 Ω Special: the multiplier and tolerance are always the last two! Brown – Brown - Red – Red – Gold 11 200 Ω ±5%Boost MeBoost me for more!
