Chart Reference FAQ

What are E12 and E24 series resistors?

E12 and E24 are standard series that define which resistance values are manufactured. E12 has 12 values per decade (for ±10% tolerance), while E24 has 24 values per decade (for ±5% tolerance). These series ensure that the maximum gap between available values doesn't exceed the tolerance of the resistors.

How do I remember the resistor color code?

Common mnemonics include "Bad Boys Race Our Young Girls But Violet Generally Wins" for Black, Brown, Red, Orange, Yellow, Green, Blue, Violet, Grey, White (0-9). However, using our interactive chart and practicing with real resistors is the most effective way to memorize the color codes.

Why are certain resistance values not available?

Resistor manufacturers follow standard series (E12, E24, E48, E96, E192) to limit the number of different values they produce. These series are mathematically designed so that the tolerance bands of adjacent values just touch, providing complete coverage while minimizing inventory requirements.
