Resist Calc

Resistor Calculator

A simple four band resistor calculator, useful for Raspberry Pi, Arduino or other electronic projects.

First Band

Black (0) Brown (1) Red (2) Orange (3) Yellow (4) Green (5) Blue (6) Violet (7) Grey (8) White (9)

Second Band

Black (0) Brown (1) Red (2) Orange (3) Yellow (4) Green (5) Blue (6) Violet (7) Grey (8) White (9)

Third Band (Multiplier)

Black (0) Brown (1) Red (2) Orange (3) Yellow (4) Green (5) Blue (6) Violet (7) Grey (8) White (9)

Fourth Band (Tolerance)

Brown (±1%) Red (±2%) Gold (±5%) Silver (±10%)

The resistor's value is 0 Ω with a tolerance of ± 0%
