Version History of OHMs Law Calc

2.1

October 24, 2023

New version adds support for additional devices and resolvers some on screen keyboard issues

1.51

March 21, 2015

This app has been updated by Apple to display the Apple Watch app icon. Adjusts visuals to be more like iOS 8

1.5

October 10, 2014

New Version adds support for Widgets! Now you can add OHM's Law Calc to the Notifications area in the Today view. Access a "Quick LAW" version right from the lock screen on ANY iOS device! Now calculating Volts, Amps and Watts is even quicker and more convenient!

1.4

September 26, 2014

Updated to support all the different versions of iPhone (4s --> 6+) Updated UI elements for cleaner look Updated UI for cleaner rotation Updated with support for iOS 8

1.3

October 24, 2012

1. Found and removed a restriction that kept the app from opening in landscape mode 2. Added the ability to tap any field and have the system automatically select the proper ohm's law wedge. For example, for volts and amps, simply tap on volts, enter your value and then tap on Amps and enter your value. It's that simple! 3. Added a field for Full Load Amps in Three Phase 4. Added a readout for Phase to Phase resistance, which calculates the series-parallel circuit caused by a three phase load when attempting to measure the resistance between one phase (of the load) and the other (eg, putting one probe on L1 and one probe on L2, or L1 & L3 or L2 & L3). 5. Changed the iPhone and iPad "tap on text" behavior to auto select the text in the text box so the user can either type new information in (without having to erase the old first) or select done to leave the old information in the box (in case the user tapped there by mistake) 6. Added support for iOS 6

  • Quick and Easy!

    This app really does calculate Three Phase correctly... Not just using the old "lazy engineers" trick of multiplying by 1.732... But rather doing the actual VECTOR MATH to properly calculate BOTH balanced and unbalanced loads. Works great for resistive AC circuits too!
    The app does exactly what it says, makes single and three phase calculations a breeze. I'll never get the wrong Three Phase Breaker again!

  • Incorrectly calculates for AC

    Good attempt, but this calculator works 100% correctly ONLY for DC.

    For AC, it ignores Power Factor (PF), caused by ever present out-of-phase Reactive currents. All AC "Power" results are really in "Volt-Amps" (VA) not Watts.

    For 3-Ph AC it incorrectly calculates VA, when given Voltage & Current. The correct method is: V x A x 1.73 (Sq Root of 3) = VA

    Power in Watts is then:
    VA x PF = Watts

    PF is always a number between 0 & 1, with 1 being in-phase (purely resistive) current, and 0 being 90 deg out-of-phase (purely reactive) current.

    For calculations (where actual PF is unknown) a PF of 0.8 is typically used.

    Resistance alone in never the only factor in AC Circuits.
