with a variety of resistance values ranging from fractions of an Ohm () to millions of Ohms. Its temperature coefficient is 250 ppm/K (two hundred and fifty parts per milion / Kelvin). Mnemonic catchphrases to remember resistor color codes. To find resistor value, hold the resistor so that the side by side color rings are to the left. The 6 color band resistor color code black-brown-white-brown-green-black stands for 190 Ω +/-0.5%, in words: one hundred and ninety Ohms with plus/minus zero point five percent tolerance. Find color codes for resistor value or vice versa. The first resistor in the chart (with 4 bands) tells you the minimum information you can learn from a resistor.
When looking at the chart, note the illustration of three round resistors with numerous color code bands.
