Final answer:
The resistor with color bands brown, green, and red has a value of 1500 ohms, corresponding to the code where brown is 1, green is 5, and red is a multiplier of 100.
Step-by-step explanation:
The student has asked about finding the value of a resistor with color bands brown, green, and red. In resistor color coding, brown represents the number 1, green represents 5, and red is used as a multiplier of 100. To find the resistance value, you take the first two digits from the first two colors and then multiply by the factor indicated by the third color. Therefore, the resistance value is 15 (from brown and green) multiplied by 100 (from red), which equals 1500 ohms. The correct answer is A. 1500 ohms.
