RESISTOR READING EXERCISE
Before starting assembly of your solder practice project, you should be thoroughly familiar with the 4-band color
code system. Many of the resistor values will be identified by color bands and it is easy to mistake their value
if you read the colors incorrectly or read the value from the wrong end. Do the following exercise in resistor
values. Place your answer in the box beneath the resistor. Answers are on the bottom of this page.
(1) brown-green-red-gold
(3) brown-black-yellow-gold
(5) yellow-violet-brown-gold
(7) yellow-violet-black-gold
(9) orange-orange-red-gold
(11) brown-black-green-gold
(2) brown-black-orange-gold
(4) red-red-orange-gold
(6) blue-gray-orange-gold
(8) brown-blue-brown-gold
(10) green-brown-red-gold
(12) brown-gray-orange-gold
