Ohm's Law Calculator
Calculate voltage, current, or resistance with Ohm's Law (V=IR).
About the "Ohm's Law Calculator" Calculator
Ohm's Law is one of the most fundamental principles in electronics and electrical engineering. It describes the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit.
This flexible tool allows you to calculate any of these three values by providing the other two. It's an indispensable companion for students, hobbyists, and professionals working with circuits.
The three Ohm's Law formulas:
- Voltage (V) = Current (I) × Resistance (R)
- Current (I) = Voltage (V) / Resistance (R)
- Resistance (R) = Voltage (V) / Current (I)
Formula Used
- V=Voltage (Volts)
- I=Current (Amps)
- R=Resistance (Ohms)
