TalentJR

Remember (Digit, digit, zeros): black 0 · brown 1 · red 2 · orange 3 · yellow 4 · green 5 · blue 6 · violet 7 · grey 8 · white 9. Band 1 and band 2 = two digits; band 3 = number of zeros to add. Examples: brown-black-red = 1000 Ω; yellow-violet-brown = 470 Ω; red-red-red = 2200 Ω = 2.2 kΩ.
