In resistor color codes, what digit does orange represent?

• A. 0
• B. 3
• C. 4
• D. 7

Answer: (B)

Orange represents the digit 3 in the standard resistor color code. The colors map to digits as black 0, brown 1, red 2, orange 3, yellow 4, green 5, blue 6, violet 7, gray 8, white 9. This 0–9 mapping is used for the resistor’s significant digits (with the third band as the multiplier). So orange stands for 3, while black would be 0, yellow 4, and violet 7. For example, a resistor with orange and black as the first two bands would start with 30, and applying the multiplier band would give the final value in ohms.
