A gold or silver band after the first bands indicates tolerance, and a quality band may follow the tolerance band.

A gold or silver band after the first bands indicates tolerance, and a quality band may follow the tolerance band.

• A. True
• B. False
• C. Sometimes
• D. Never

Answer: (A)

In resistor color codes, the bands tell you the value and how precise it is. The first bands give the significant digits and the multiplier, and the band that comes after them gives the tolerance. Gold and silver are the tolerance colors, representing ±5% and ±10% respectively. On many resistors, you’ll also see an extra band after the tolerance on higher-precision parts; this is the quality (or temperature-coefficient) band. It provides additional information about how the resistor behaves with temperature or over time. So, seeing a gold or silver tolerance band and then potentially a quality band after it is exactly how these components are described, making the statement true.
