A carbon resistor has the following color bands; band 1 is yellow, band 2 is violet, band 3 is gold, and band 4 is silver. What is the ohmic value of the resistor, as well as the tolerance? See illustration EL-0103.
• Resistor color code chart in the illustration (first and second digit, multiplier, tolerance) • Meaning of yellow, violet, gold, and silver in the table • How to convert the final number into ohms vs kilo-ohms (kΩ)
• What digits do yellow and violet represent according to the table, and how do these form the base number? • What multiplier value does a gold band represent, and how does that change the base number? • What tolerance percentage does a silver band indicate, and which answer choices match that tolerance?
• Verify in the chart what yellow and violet mean for the 1st and 2nd digit columns • Verify what value gold has under the Multiplier column (note it is less than 1) • Verify which answer choices have the same tolerance as the silver band, then see which one matches your calculated resistance
