In the Brown-Black-Red-Gold example, which color in the third position represents the multiplier?

Explanation:
In a four-band resistor color code, the first two bands give the significant digits, the third band is the multiplier, and the fourth band is the tolerance. For Brown-Black-Red-Gold, the first two bands yield 1 and 0, so the digits are 10. The third color, Red, is the multiplier and it means 100 (10^2). Multiply 10 by 100 to get 1000 ohms (1 kΩ). The fourth band, Gold, indicates a tolerance of ±5%. The key idea is that the third position sets the multiplier, and Red specifically corresponds to a multiplier of 100.
