Ohm's Law Calculator

Does NOT work anymore and the developer is not attending to it anymore. Old review-> Need to change fields to empty or when onClick listener happens, it's annoying having to manually delete the zero,but other than that it's nice and simple

Reset doesn't just reset numbers to "0", which you have to back space to clear before entering your value, it also resets to a default measure selection so that has to be changed back also to the one you were using. So if you were using A(amps) and ohm it changes back to mA and K-ohm every time. So if you don't watch for that your results will be off by factor of ?? 100 or 10 or ? Guessing with the extra hassle you will find the next calculator out there to be quicker.

As others have said, the 0 in the fields is a pain to delete and having to reset to recalculate sux

Input Voltage & Resistance. Calculates Power incorrectly by a factor of 100.

Won't recalculate if you change an option, you must start over.

This may be the best app ever. This, or the developer's QB passer rating calculator. I'm torn. They are just so amazing! No relation to the author. I promise. Okay?

It is simple, small, and does exactly what it is supposed to do.

Doesn't calculate power correctly. Volts x amps =watts.

Not bad. 2 errors in diagram. In Volts, shows V=PR. Should be V=square root of PR. Also in Current, shows I=P/R. Should be I=square root of P/R.

The only ohms law calculator I found that let me define 3 parameters and let the calculator define the fourth. Thank you

Simple interface, equations included.

Is a bummer that you need to reset each time you want to do a new calculation. Reason why I mention this is because the units default back smaller and I need to adjust to amps and watts.
