Ohmulator is a powerful electric circuit calculator designed to simplify the application of Ohm's Law. Developed by Armchair Engineering, this utility is available for iPhone and macOS. With a stylish design and intuitive interface, Ohmulator allows users to quickly find the unknown variables of a circuit.

One of the standout features of Ohmulator is its ability to easily adjust unit types on the fly. Whether you're working with milli Amps, Amps, or kilo Amps, there's no need for prior conversion. Simply enter two known variables from current (I), resistance (R), voltage (V), or power (P), set your preferred units, and Ohmulator will swiftly calculate and display the previously unknown values.

In addition to its circuit calculation capabilities, Ohmulator also serves as an effective total resistance calculator. This versatile tool is a must-have for radio amateurs, electronic enthusiasts, and anyone working with electrical circuits.
