Electrical
Ohm's Law Calculator
Calculate any variable of Ohm's Law: voltage (V), current (I), or resistance (R).
These calculators provide estimates and educational results. Always verify critical engineering calculations against applicable standards and qualified professional review.
Formula
V = I × R
Ohm's Law states that the voltage across a conductor is directly proportional to the current flowing through it.
