Ohms Law Power Law Calculator is a free iPhone application developed by Cressall Resistors Ltd. It falls under the Utilities & Tools category and is available in multiple languages, including English, French, German, Swedish, Russian, Polish, Spanish, Italian, Chinese (Traditional & Simplified).

This application is designed to help users understand and calculate the relationship between voltage, current, resistance, and power in electrical circuits. It allows users to input values for any two parameters and calculates the remaining two. Users can lock one parameter and input another to quickly recalculate different scenarios.

The app features a keypad for value input and a padlock symbol to indicate the fixed parameter. Users can easily change the fixed parameter by tapping on it or dragging the padlock. Long-pressing a parameter freezes it, allowing users to modify the other three parameters. To unfreeze, simply tap on any other parameter.

Overall, Ohms Law Power Law Calculator is a useful tool for anyone working with electrical circuits, providing quick and accurate calculations for Ohm's law and power law equations.
