Which color band indicates a 5% tolerance on a resistor?

• A. Gold
• B. Silver
• C. No color band
• D. Red

Answer: (A)

Understanding resistor tolerance bands is essential. The tolerance band shows how much the actual resistance can vary from the stated value. A gold band in this position means a tolerance of ±5%. So the resistor’s real value can be within five percent above or below its labeled resistance. For comparison: a silver tolerance band means ±10% variation, having no color band typically indicates about ±20%, and red can indicate ±2% tolerance on some resistors. But for this question, the gold band corresponds to the 5% tolerance.
