🔍 Key Concepts

• Use the first two color bands as the first and second digits of the resistor value. • Use the third color band as the multiplier, meaning a power of 10 taken from the chart in the illustration. • Use the fourth band (gold or silver) to determine the tolerance percentage from the chart.

💭 Think About

• What digit does yellow represent, and how does that apply to both the first and third bands in this problem? • After you form the two-digit number from the first two bands, how does multiplying by the third band’s power of 10 change the number of zeros? • Which answer choices match the tolerance color given in band 4, and which can you immediately rule out?

✅ Before You Answer

• Verify from the chart what yellow equals as a digit and as a multiplier (power of 10). • Confirm which color corresponds to ±5% and which to ±10% tolerance using the table. • After applying the multiplier, check that your final value’s number of zeros is consistent with one of the choices before deciding.
