Apakah Resistor?

A resistor is an electrical component that limits or controls the flow of electric current in a circuit. Resistance is measured in ohms (Ω) and is usually shown by colored bands on the resistor body. This tool helps you decode those color bands, combine resistors in series or parallel, and calculate power dissipation — all for free.

Kod Warna: R = (digits) × multiplier ± tolerance%

Siri: R_total = R1 + R2 + R3 + …

selari: 1/R_total = 1/R1 + 1/R2 + 1/R3 + …

kuasa: P = V² / R  |  I = V / R

Resistor Color Code Chart

• Black=0, Brown=1, Red=2, Orange=3, Yellow=4

• Green=5, Blue=6, Violet=7, Gray=8, White=9

• Gold multiplier = ×0.1, Silver multiplier = ×0.01

• Toleransi: Coklat ±1%, Merah ±2%, Emas ±5%, Perak ±10%

Quick Examples

• Coklat-Hitam-Merah-Emas = 10 × 100 = 1000 Ω (1 kΩ) ±5%

• Dua perintang 100 Ω dalam siri = 200 Ω

• Dua perintang 100 Ω selari = 50 Ω

• 12 V merentasi 100 Ω = 1.44 W pelesapan kuasa

Nota Penting

  • All resistance values must be greater than zero.
  • Color bands are read from left to right — the tolerance band is usually gold or silver.
  • Unit conversions are done automatically — just pick your preferred unit.
  • At least two resistors are needed for series and parallel calculations.
