    Tutorial: Step by step
    General Info: When Ohm’s Law Calculator Ad Free is first opened all fields are reset. Only two of the field should be checked at one time. For the equations to work two of the four variables need to be known and entered correctly.
    Step 1: Enter a known variable into a field. Insure that the metric prefix is correct as this can greatly affect the equations outcomes. The field should turn green.
    Step 2: Enter the second known variable into a field. Again, insure that the metric prefix is correct and the field should turn green.
    Step 3: The remaining fields will turn blue and will contain the correct solutions.
    Note: If three variables are checked they will turn red and wait for one to be unchecked to continue.

    Q: What equations does ohms law calculator follow?
    A: This ohms law app follows the standard ohms law triangle and the power triangle.

    Q: How do I add more significant digits to my results?
    A: To add more than the default three digits add zeros to the end of your inputs (ie, 3.2300) and the results will match the inputs significant digits.

    Q: Are we adding functions in the future?
    A: This app was designed to fit my requirements for my career. If you need extra functions like AC ohms law equations send me an email at and I will add these features in future updates if enough interest is shown.

    Q: How do I submit suggestions or problems about the ohms law calculator?
    A: The best way is to send an email to
