In a 4-band resistor color code, which band indicates tolerance?

Explanation:
Tolerance is shown by the last band in a 4-band resistor color code. The first two bands give the digits of the resistance, the third band is the multiplier that scales those digits, and the fourth band specifies how much the actual resistance may vary from the stated value. For example, a resistor with brown, black, red, gold reads 10 × 100 = 1,000 ohms with a tolerance of ±5%. If the last band is silver, the tolerance is ±10%. This is why the last band carries the tolerance information.
