Using color bands Green-Blue-Red-Gold, which is the resistance and tolerance?

Explanation:
The main idea is how to read 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. Green corresponds to 5 and Blue to 6, so the two digits are 56. The third band, Red, means multiply by 10^2 (100). So 56 × 100 = 5600 ohms, which is 5.6 kΩ. The fourth band, Gold, indicates a tolerance of ±5%. Therefore, the value is 5.6 kΩ with ±5% tolerance.
