Clear, practical electrical engineering tools for learning and real-world use.
Ohm’s Heaven is an educational platform created for students, technicians, and young engineers learning electrical engineering. Our goal is to provide clear, reliable, and practical tools for studying, experimenting, and applying fundamental electrical concepts.
We focus on calculators and references that explain not only the result, but also the theory behind it. Every tool is designed to be intuitive, transparent, and grounded in real physics.
Current tools include ampacity estimation, voltage drop calculation, resistance calculation, with many more planned.
Calculations provided on this website are intended for educational and learning purposes. While we aim for correctness and clarity, results should not replace official standards, manufacturer data, or professional engineering judgment.
