एक अवरोधक क्या है?

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.

All Formulas at a Glance

रंग कोड: R = (digits) × multiplier ± tolerance%

शृंखला: R_total = R1 + R2 + R3 + …

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

शक्ति: P = V² / R  |  I = V / R

4 Calculation Types

रंग कोड

किसी प्रतिरोधक पर 4-बैंड, 5-बैंड, या 6-बैंड रंग कोड से प्रतिरोध को डिकोड करें।

श्रृंखला प्रतिरोध

Calculate total resistance when resistors are connected end to end.

समानांतर प्रतिरोध

Calculate total resistance when resistors are connected side by side.

शक्ति का अपव्यय

वोल्टेज और प्रतिरोध का उपयोग करके पता लगाएं कि एक अवरोधक कितनी शक्ति नष्ट करता है।

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

• सहनशीलता: भूरा ±1%, लाल ±2%, सोना ±5%, चांदी ±10%

Quick Examples

• भूरा-काला-लाल-सोना = 10 × 100 = 1000 Ω (1 kΩ) ±5%

• श्रृंखला में दो 100 Ω प्रतिरोधक = 200 Ω

• समानांतर में दो 100 Ω प्रतिरोधक = 50 Ω

• 100 Ω के पार 12 V = 1.44 W बिजली अपव्यय

महत्वपूर्ण नोट्स

  • 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.
