Publisher 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.
