❓ Frequently Asked Questions

How do I read a resistor color code?
For 4-band resistors: 1st & 2nd bands are digits, 3rd is multiplier, 4th is tolerance. For 5-band: 1st-3rd are digits, 4th multiplier, 5th tolerance. Our calculator does this automatically.
What is the difference between 4, 5, and 6 band resistors?
4-band: 2 digits + multiplier + tolerance (common). 5-band: 3 digits + multiplier + tolerance (precision). 6-band: 3 digits + multiplier + tolerance + temperature coefficient (high precision).
What does the tolerance band mean?
Tolerance indicates how much the actual resistance can vary from the stated value. Gold = ±5%, Silver = ±10%, Brown = ±1%, Red = ±2%.
What is the resistor color code order?
Standard order: Black(0), Brown(1), Red(2), Orange(3), Yellow(4), Green(5), Blue(6), Violet(7), Grey(8), White(9). This is remembered by the mnemonic "BB ROY G. BIV".
