## Description

Decode color bands, convert SMD markings, browse E-Series values, and solve resistor circuit calculations in one focused toolbox.

Resistor Calculator is a practical offline toolbox for electronics students, makers, repair technicians, and engineers who work with resistors and common circuit calculations.

Decode resistor color bands, convert resistance values into color bands, read SMD resistor markings, browse E-Series values, and solve everyday resistor-related circuit problems in one focused app.

RESISTOR TOOLS

• Decode 3, 4, 5, and 6-band resistors
• Convert resistance values into color bands
• Support engineering notation such as 4.7k, 4k7, 2M2, and 0R22
• Calculate tolerance, minimum, and maximum resistance
• Show temperature coefficient for 6-band resistors
• Reverse resistor reading direction
• Copy, share, save, and reset results

SMD RESISTOR CODES

• Decode 3-digit and 4-digit SMD codes
• Support R, K, and M notation
• Support EIA-96 markings
• Handle zero-ohm resistors
• Convert resistance values back into suitable SMD codes
• Explain decoded values clearly

E-SERIES VALUES

• Browse E6, E12, E24, E48, E96, and E192 values
• Find the nearest standard resistor values
• Compare error and tolerance ranges
• Open selected values directly in resistor tools

CIRCUIT CALCULATORS

• Series and parallel resistance
• Ohm’s Law
• Voltage divider
• LED current-limiting resistor
• Target resistance combinations
• Wheatstone bridge
• Op-amp gain
• Star / Delta conversion
• Wire resistance
• Voltage drop
• Pull-up / Pull-down resistor
• RC time constant

LIBRARY WORKFLOW

• Save calculation history
• Add results to Favorites
• Organize values and calculations into Projects
• Export project data as CSV, JSON, or plain text
• Review saved calculations later

BUILT FOR DAILY ELECTRONICS WORK

Resistor Calculator is designed to be fast, clear, and focused. Results update immediately as you enter values, and formulas are available when you need to understand how a calculation was made.

All core calculations run on your device and the app works without an account or internet connection.
