About OhmLab
Our Mission
OhmLab was created with a simple mission: to help physics and electronics students understand resistance concepts clearly and accurately. We believe that learning should be accessible, straightforward, and supported by reliable tools.
What We Offer
We provide a suite of free calculators designed specifically for students learning about electrical circuits and resistance. Our tools include:
- Resistor Color Code Calculator - Decode 4-band and 5-band resistor values
- Series Resistance Calculator - Calculate total resistance in series circuits
- Parallel Resistance Calculator - Find equivalent resistance in parallel circuits
- Voltage Divider Calculator - Determine output voltages in divider circuits
Educational Purpose
All calculators and information on OhmLab are provided for educational purposes only. We strive for accuracy in all our calculations and explanations, helping students verify their homework, understand concepts, and learn by doing.
Our Approach
We focus on three key principles:
- Accuracy: Every calculator uses correct formulas and provides reliable results
- Simplicity: Clean, easy-to-use interfaces that don't overwhelm
- Education: Clear explanations that help you understand the concepts, not just get answers
