Ohm's law

To use the calculator you need to enter any two of three values and the calculator will compute the third one (if it is mathematically possible). For example: you can enter the voltage U, next the current I (don't forget to select proper units), select the unit for the result and click "Compute R" to compute the resulting resistance.


U =
   



I =
   



R =
   



P =
 


automatically select unit for result
