Ohmulator is a simple, yet robust, electric circuit calculator that enables you to quickly and easily find the unknown variables of a circuit, using Ohm's Law.
Ohmulator allows you to easily adjust unit types, for input and output values, on the fly (eg. millivolts, volts, kilovolts), which means no prior conversion.
Enter two known variables (from: I = Current, R = Resistance, V = Voltage, P = Power), set preferred units, and Ohmulator will calculate and return the previously unknown values.
Ohmulator is also an effective (total) Resistance calculator for up to four resistors in series or parallel.
Also available for iPhone & iPad.
What two app store reviewers had to say about Ohmulator for iOS:
"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
