In a resistor, which color band typically indicates the unit of measurement?

In resistor color coding, the unit of measurement, which represents the multiplier in significant figures, is indicated by the color of the first band. The color black corresponds to the number 0, which is used to represent a multiplier of (10^0) or 1, thus denoting the base unit.

Understanding this allows for the interpretation of resistor values in a straightforward manner. Resistors are often identified not just by their resistance value but also in how the colors on the bands correspond to numbers. Each color corresponds to a specific digit according to the standard resistor color code chart.

Colors like red, yellow, and brown correspond to different numeric values (red being 2 for (10^2), yellow being 4 for (10^4), and brown being 1 for (10^1)), but none of these directly indicate the base unit in the same way black does for resistance multipliers.
