## Ohm's Law Pro

This application consists of three parts.

The first one, "Ohm's Law", explains one of the fundamental laws of physics - the Ohm's law.

The second one, "Resistor Colorband Decoder", provides the possibility of calculating the value of the resistor using colors of the bands painted on it. Three, four,five and six band decoders are available. Inverse converter (for calculating the colors of the bands) is also provided.

The third part of the app is dedicated to the voltage divider.

The user interface is very simple and intuitive.

Note: If you are having problems entering decimal numbers because your onscreen keyboard does not show a period or a comma, here is the solution: Go to the settings tab and set input type to text. This will give you a full keyboard. The keyboard is different from device to device, so I had to make it user selectable.

## Ohm Help

This preliminary version of Ohm Help will calculate Volts, Resistance and Current for a given circuit and can calculate requirements for LED volt drop resistors.

Ohms Law - enter any two values and it will calculate the third

Led Volt Drop - enter any three values and it will calculate the remaining

Double tap a field to delete a value

This is just a test version and an update will be soon to add more functions like Wattage to the Ohm calculator, available standard resistors and their colour codes to the LED volt drop section and hopefully more formulas and helpful information for engineers.
