Final answer:
A resistor with the color bands Brown, Orange, Yellow, Gold has a nominal resistance of 130 kilohms (Ω5%).
Step-by-step explanation:
The nominal resistance of a composite resistor marked with the color bands Brown, Orange, Yellow, Gold can be determined using the color code table for resistors. According to this code, the first two bands represent the first two digits of the resistance value, the third band represents the multiplier, and the fourth band represents the tolerance. In this case, the following colors correspond to the following values: Brown represents 1, Orange represents 3, and Yellow represents a multiplier of 10,000. Therefore, the resistance is calculated as follows:
- Brown (1) as the first digit.
- Orange (3) as the second digit.
- Yellow multiplier (10,000).
Combining the digits and multiplier gives us a resistance value of 13 x 10,000 Ω or 130 kΩ (130 kilohms). The Gold band represents a tolerance of ±5%, indicating that the actual resistance can vary by ±5% from the nominal value.
