About this app

Ohm Finder is a practical and intuitive tool for quickly calculating resistor values using the color code. Ideal for students, engineers, and electronics enthusiasts, the app allows you to input the color bands of a resistor and instantly find out its value in ohms.

Main Features:
• Simple and easy-to-use interface
• Four-band resistor (2 digits, multiplier, tolerance)
• Five-band resistor (3 digits, multiplier, tolerance)
• Six-band resistor (3 digits, multiplier, tolerance, temperature coefficient (PPM))
• SMD resistor: (3-digit EIA, 4-digit EIA, EIA-96)
• Fast and accurate calculation of resistance values and ranges
• Tolerance and temperature coefficient visualization
• Calculation history for easy reference
• Learning mode for the color code system
• Resistor combination series and parallel
• Voltage divider

Whether you're a professional or a hobbyist, Ohm Finder makes working with resistors easier by eliminating the need to memorize color combinations and values. Everything you need is right in the palm of your hand!
