## What is Ohm's?

Ohm's Law Calculator
------------------

Updated for iOS 7!

In this app, input two out of four inputs and the calculator will solve for the unused inputs using Ohm's Law. 

For example, input numbers for the ‘V’ and ‘I’  and the calculator will solve for variables ‘R’ and ‘P’, where R = (V/I) and P = (I*V).

Another example, input numbers for ‘I’ and ‘R’ and the calculator will solve for variables variables ‘P’ and ‘V’, where P = (I2*R) and V = (I*R).

## Key features

- Calculate Ohm's Law values
- Input any two variables
- Solves for remaining inputs
- Supports voltage, current, resistance, power
- Updated for iOS 7

### 1/5 — App doesn't work!

*2013-09-26*

APP doesn't work, says to input two values, I put in two values, then it says to only out in two values.

### 5/5 — Best Ohms law calculator EVER made!!!

Great job. I love the option to see all the formulas.

## Frequently asked questions about Ohm's

### What is Ohm's calculator?

Ohm's is a utility app that helps you calculate electrical values using Ohm's Law. You input two known values, and it solves for the other two variables: voltage (V), current (I), resistance (R), and power (P).

### How does Ohm's calculator work?

The app allows you to input any two of the four main electrical values (V, I, R, P). It then uses the relevant Ohm's Law formulas (e.g., R = V/I, P = I*V) to calculate the missing values.

### What electrical values can Ohm's calculator compute?

Ohm's calculator can compute voltage (V), current (I), resistance (R), and power (P). You provide two of these, and the app finds the other two.

### Is Ohm's calculator free?

No, Ohm's calculator is a paid app. It was priced at $0.99 at the time of its last update.

### What devices does Ohm's calculator support?

Ohm's calculator is designed for iOS devices, specifically iPhones and iPods. It was updated to be compatible with iOS 7.
