Electronics calculators

IEC 60062 resistor colors, LED current-limiting resistors, and two-resistor dividers. These are circuit-planning figures, not a substitute for a datasheet.

Resistors and LEDs

Band decoding and Ohm’s law for a single series string.

Resistor Color Code Calculator

Reads 4, 5, and 6 band resistors and converts a value back to colors.
