## What is Resistor Value Calculator?

Resistor Value Calculator is a comprehensive electronics engineering tool for engineers, hobbyists, and students.

Features:
• Color Band to Value Calculator — supports 3, 4, 5, and 6-band resistors with real-time visualization and smart auto-sequence input.
• Reverse Lookup — enter a resistance value to find matching color band combinations.
• SMD Code Calculator — decode 3-digit, 4-digit, and EIA-96 SMD resistor codes.
• LED Current-Limiting Resistor Calculator — compute the correct resistor for LEDs with series/parallel configurations and common LED presets.
• Series/Parallel Network Calculator — calculate equivalent resistance for series and parallel resistor networks.
• E-Series Standard Preferred Values Table — browse IEC 60063 E6 through E192 series with search.
• Save and export resistor presets to CSV from local history.
• Dark and light theme support.

All calculations follow IEC 60063, EIA-96, and standard E24-E192 conventions. No account or login required — works entirely offline on your device.
