What is the Ohm’s Law Calculator?

The Ohm’s Law Calculator helps you calculate voltage, current, or resistance in an electrical circuit using the well-known Ohm’s Law formula (V = I × R). By entering two of the three values, the calculator automatically computes the unknown quantity. This tool provides quick and accurate results, making it easy for students, engineers, and hobbyists to analyze circuits without manual calculations. It also shows results clearly in a dedicated result box, ensuring you can track and verify your calculations efficiently.

How to Use:

1. Enter Voltage (V): Type the voltage of the circuit in volts, or leave it blank if unknown.
2. Enter Current (I): Input the current in amperes, or leave it blank if unknown.
3. Enter Resistance (R): Type the resistance in ohms, or leave it blank if unknown.
4. Click “Calculate”: The calculator will compute the missing value based on the two inputs you provided.
5. Review the Result: The result box displays the calculated value clearly. Use this to check circuit parameters, plan experiments, or verify theoretical calculations.
