Ohm’s Law Calculator: Your Essential Electrical Engineering Tool

The Ohm’s Law Calculator is a powerful yet user-friendly web application designed to simplify electrical calculations for professionals, students, and hobbyists. Based on the fundamental principle V = I × R (Voltage = Current × Resistance) and its power derivative P = V × I, this tool instantly computes missing electrical values when any two parameters are provided.

Key Features:

✅ Smart Calculation – Automatically determines voltage (V), current (I), resistance (R), or power (P) with just two inputs
✅ Multi-Unit Support – Works with diverse units including volts/kV/mV, amps/mA, ohms/kΩ/MΩ, and watts/kW/MW/horsepower/BTU
✅ Educational Breakdown – Shows step-by-step solutions to help users understand the underlying math
✅ Professional-Grade Accuracy – Delivers precise results with 4 decimal places
✅ Responsive Design – Adapts seamlessly to desktops, tablets, and mobile devices

Perfect For:

• Electrical engineers performing quick circuit analysis

• Students learning foundational electronics concepts

• DIY enthusiasts working on electronics projects

• Educators demonstrating Ohm’s Law principles

With its intuitive purple-and-white gradient interface and instant calculations, this tool eliminates manual computation errors while making electrical theory accessible to everyone.
