What is the Ohm's Law Calculator?
The Ohm's Law Calculator computes the voltage across a conductor given the current and resistance (V = IR).
How to Use This Calculator
1
Enter the current in Amperes (A).
2
Enter the resistance in Ohms (Ω).
3
Click 'Calculate' to find the voltage in Volts (V).
Example Calculation
Current = 2 A, Resistance = 10 Ω
Voltage = 2 * 10 = 20 Volts.
Frequently Asked Questions
Pro Tips
- Remember the triangle: V on top, I and R on bottom.
- High resistance means less current flows for the same voltage.
