Resistor color code

Bands ↔ value: 4- and 5-band code + tolerance

Value, Ω

4 bands: 4.7 kΩ

Yellow + Violet + Red + gold (5%)

5 bands

Yellow + Violet + Black + Brown

Reading: first bands are digits, second-to-last is multiplier, last is tolerance (gold 5%, silver 10%, brown 1%). Hold the resistor with tolerance on the right.
