Ohm's Calculator allows you to enter any two values of resistance, amperage, voltage, or power and receive the remaining two values via Ohm's Law.

Perfect for Electrical Engineering students or professionals, enter in the voltage, amps, ohms, or watts and receive the answers you need quickly! This app includes quick-buttons with standard increments of units/items in each category.

These quick-buttons come in real handy. For instance, for a 660 ohm resistor, simply, tap the 330 button twice instead of having to pull up the keypad and type it in.

An improvement over other Ohm's Law applications, this app allows you to clear only the two output values so you don't have to reset all the values and start over every time you want to change only one entry.

In the value boxes you'll see a green dot for values that were manually entered so you don't forget which ones are 'fixed' when evaluating the results.

Thanks for using Ohm's Calculator!
