Ohm's Law Calculator

About this app

This calculator will calculate power, voltage, current and resistance. The user is prompted for the appropriate values depending on the equation selected on the wheel.
What were the results of that power calculation I did just a minute ago? Don't worry. Just swipe over to the next screen and you will find it listed under history.

Ratings and reviews

Not my favorite. There are other apps that allow for faster information entry. This is more like having to walk out of one building, then find the one you need. Then hopefully still remember what you were doing. Other apps allow for changing check boxes, drop your new numbers into the blanks and go.

Just entered 66k with 12V trying to calculate the current and it's showing 0. I understand that the result is very small, but 180 µA is not an outrages number when it comes to electronics. Another inconvenience is that it's using a standard keyboard, which covers the user interface.

Slight learning curve remembering which of the formulas that I needed each time. It does have an issue when you want to do more than one calculation using the same formula but overall it's a crisp, clean, user friendly app.

What’s new

This release is an update that provides compatibility with newer API levels. Also the calculate button has been relocated to be accessible without closing the keyboard.
