Brown is __. (band code)

Brown is __. (band code)

• A. 0
• B. 1
• C. 2
• D. 3

Answer: (B)

In the resistor color code, colors map to digits: black 0, brown 1, red 2, orange 3, yellow 4, green 5, blue 6, violet 7, gray 8, white 9. Brown, in this scheme, represents the digit 1. This mapping is used to read resistance values from the bands, with brown meaning 1 when it’s in a digit position (and 10 when it’s used as a multiplier, i.e., 10^1). So Brown is 1. For example, a resistor coded with first digit 1 and second digit 0 would start with 1 and 0, and a multiplier of red (×100) would yield 1000 ohms. The essential point is memorize that brown equals 1.
