# [iPhone] Electrical ToolKit helps you calculate common physics and engineer equations with ease

[1]Electrical ToolKit is an incredibly useful iPhone app developed by Niranjan Kumar. If you’ve ever needed a handy reference for calculating ohms, resistance, wattage, or anything else related to electrics, this handy app has got you covered.

### What is it and what does it do

Main Functionality

Electrical ToolKit is designed to appeal to electricians, electrical engineers, science students, theatrical lighting designers, and more. You simply input your values, and the app does all the tricky calculations for you. Some of the calculations Electrical ToolKit can do include calculations related to Ohm’s Law, as well as Power Triangles and Star Delta Transformation.

Pros

• Way easier than doing these calculations by hand (trust me, I had to in college, and it was the WORST)
• Simple, straightforward design that’s easy to comprehend and navigate
• Updated occasionally with new tools

Cons

• Somewhat niche content: may be hard for those without a basic background in electrics to get their bearings at first
• Could be improved by sorting formulas/calculations by situation or profession that is most likely to use them

Discussion

[2]Electrical ToolKit would have saved me hours of headaches in college. Part of my course work (and work study duties) revolved around lighting design for the Theatre Department. It was a ton of fun, but doing the calculations to make sure I wasn’t going to overload the circuits was also a stressful nightmare.

This app is designed to appeal to a wide variety of people who need to make calculations regarding electricity. Whether you’re baffled by series circuits, parallel circuits, resistors, or something else entirely, this handy app can probably help you. Ohm’s Law has never been so easy to deconstruct.

Thanks to a simple, straightforward look, this app is very easy to navigate. I also really appreciated the fact that each calculator tool is paired with a visual aid that illustrates things more clearly. Hooray for diagrams!
