What numerical multiplier does the orange third band represent in resistor color codes?

• A. 1000
• B. 10
• C. 100
• D. 10000

Answer: (A)

On resistor color codes, the first two bands give the significant digits and the third band is the multiplier. Orange corresponds to the digit 3, and as the multiplier that means 10 raised to that power, so 10^3 equals 1000. Therefore the orange third band represents a multiplier of 1000. For example, if the two significant digits are 47, the resistance would be 47 × 1000 ohms = 47,000 ohms.
