What does the silver resistor band indicate in terms of tolerance?

• A. ± 5%
• B. ± 15%
• C. ± 10%
• D. ± 2%

Answer: (C)

The silver resistor band indicates a tolerance of ± 10%. In resistor color coding, each color corresponds to a specific value or tolerance, and the band colors follow a standardized chart. Silver specifically denotes a tolerance of ± 10%, meaning that the actual resistance can vary by 10% above or below the stated value. This is important for electronic circuits where precise resistance values can affect performance. Understanding these tolerance values helps technicians ensure that electronic components meet the necessary specifications for reliability and function. Regarding the other tolerance values linked to the other colors—± 5% is represented by a green band, ± 15% by a brown band, and ± 2% by a red band—these do not correspond to the silver band, thus allowing it to stand out as the choice representing a tolerance of ± 10%.
