180r 180 ohm resistor colour code. The only exception to this is the zero ohm resistor which has only one black band and no others. Resistors Springerlink Resistor Colour Code Wheel For Resistor Colour Codes Smitty S Super Speed Drill For Memorization No 2 Resistor Gray black black would be an 80 ohm resistor. 80 ohm resistor color code . Gray black black was the original answer to the question of the color code on a 8 ohm resistor but that is wrong. The value is thus 56100 5600 w. Lets try a few practice problems to hone our skills at deciphering resistor color code. In the example on the left these bands are green blue red and gold. 4 band colour code system. Enter the resistor value like 120000 for 120 k ohms. 82 ohm 82r gray red black 100 ohm 100r brown black brown 120 ohm 120r brown red brown 150 ohm 150r brown green brown ...
