Description

⚡ Ohm’s Law Calculator – Solve Voltage, Current, Resistance, and Power

The Ohm’s Law Calculator helps you easily determine the relationship between voltage (V), current (I), resistance (R), and power (P) in electrical circuits. It is an essential tool for students, electricians, engineers, and hobbyists working with electronics and electrical systems.

📘 What It Calculates:

  • ✅ Voltage (V = I × R)

  • ✅ Current (I = V ÷ R)

  • ✅ Resistance (R = V ÷ I)

  • ✅ Power (P = V × I or I² × R or V² ÷ R)

💡 Features:

  • Simple input of two known values to find the other two

  • Supports both DC and AC circuits (basic calculations)

  • Useful for circuit design, troubleshooting, and analysis

  • Converts units automatically for practical use

👤 Who Should Use This:

  • 📌 Students learning electrical fundamentals

  • 📌 Electricians diagnosing circuits

  • 📌 Engineers designing electrical systems

  • 📌 DIY enthusiasts working on electronic projects

✅ Pro Tip:

Remember: If two values are known, the other two can always be calculated using Ohm’s Law formulas.

🔗 Related Tools:

Ohm’s Law states that the current through a conductor is directly proportional to the voltage across it and inversely proportional to resistance (V = I × R).

Georg Simon Ohm, a German physicist, discovered it in 1827

It helps predict and control how circuits behave, making it fundamental for designing and analyzing electrical systems.
