1. The problem is to identify the color bands on a resistor that has a resistance of 1 ohm with a tolerance of plus or minus 5%. 2. The resistor color code uses colored bands to represent the resistance value and tolerance. The first two bands represent the first two digits, the third band is the multiplier, and the fourth band is the tolerance. 3. For 1 ohm, the digits are 1 and 0 (since 1 ohm is 10^0 ohms), so the first band is brown (1), the second band is black (0), and the third band is black (multiplier of 10^0 = 1). 4. The tolerance of 5% is represented by a gold band. 5. Therefore, the color bands are: brown, black, black, gold. 6. This means the resistor has a value of 1 ohm with a tolerance of ±5%.
