Ohm's Law Calculator

Ohm's Law Calculator

Formula:

Resistance (R) = V ÷ I

Current (I) = V ÷ R

Voltage (V) = I x R

Note: The resistance is the pure DC resistance. The calculator can not figure out the motors, transformers and other inductive load resistance and results.

 
Resistance R(Ω)  x Current I(A)
