## Ohmulator Description
Makes Ohm's Law simple!

Ohmulator is a simple, yet robust, electric circuit calculator that enables you to quickly find the unknown variables of a circuit.

Ohmulator allows you to easily adjust unit types on the fly (eg. milli Amps, Amps, kilo Amps), which means no prior conversion!

Enter two known variables (from: I = Current, R = Resistance, V = Voltage, P = Power), set preferred units, then Ohmulator will calculate and return the previously unknown values. 

Also an effective (total) resistance calculator.


What two App Store reviewers had to say about Ohmulator:

"Great. Does what it says. Very good app. Stylish design."  5 Stars -  Jamie1990jamie 

"Awesome app. It simply works. A must have for the radioamateur or electronic nerd. Nice to have the watt law as well." 5 Stars - Per67


Also available for macOS on the Mac App Store.

Could use way more algorithms though.

Ohmulator does everything I need it to. I mostly use it for calculating power and current on my coil builds. Helps me ensure my mod doesn't turn into a pipe bomb!

Was a five star app, new update painful to look at and less functional.
