How to read resistor color bands from left to right
Identify significant digits, multiplier, tolerance, and optional TCR before calculating an exact resistor color-code value.

Band order, precision, tolerance, and TCR
Three focused guides explain how to read significant figures and multipliers, how 4/5/6-band roles differ, and why tolerance and temperature coefficient answer separate questions.
Four, five, or six bands: what actually changes
Compare significant-digit count, multiplier, tolerance, and TCR roles across 4-, 5-, and 6-band resistor markings.
Read guideTolerance and temperature coefficient are different limits
Calculate an exact nominal tolerance range and understand why a sixth-band ppm/K code is not a power or operating-temperature rating.
