Ohm's Law & Power Calculator

Enter any two values to calculate the third and Power (P).

Calculate Electrical Parameters with MultiCalc

MultiCalc's Ohm's Law calculator helps engineers, electricians, students, and hobbyists solve electrical circuit problems. Ohm's Law describes the fundamental relationship between voltage (V), current (I), and resistance (R) in electrical circuits.
