⚡ Ohm's Law Calculator ⚡
📚 About This Tool
Welcome to the ultimate Ohm's Law Calculator! This powerful web tool simplifies electrical calculations using the fundamental principles of Ohm's Law. Designed for both beginners and professionals, our calculator helps you quickly determine voltage (V), current (I), resistance (R), and power (P) with just two known values. Ohm's Law (V = I × R) forms the foundation of electrical engineering and circuit analysis, and this tool makes applying these principles effortless.
Whether you're designing circuits, troubleshooting electrical systems, or studying electronics, this calculator eliminates manual computation errors and saves valuable time. Our enhanced version goes beyond basic Ohm's Law calculations by including power computations (P = V × I), making it a comprehensive solution for various electrical engineering scenarios. The intuitive interface and instant results make complex calculations accessible to everyone, from hobbyists to professional engineers.
