E-Formulas

The best app for electrical engineer

I work in the utility industry and find this app very useful in the field. I would like to see the ability to calculate a series/parrallel circuits resistance. And possibly see the electrical diagram drawn out on each calculator page.

Very cool. This app is very smooth and easy to use. It puts all the formulas for various electronics projects right in my hand and helps me better understand the more complex and less used formulas. The link to Wikipedia is great for further understanding how to use the formula and to better understand what's happening with relation to the project. Thanks!

This application has all the electrical formulas you need. When I first purchased this application, I thought it had everything you need except a voltage drop calculator. I sent an email to the developer and asked if they could add a voltage drop calculator based on the National Electrical Code requirements of 3 percent for branch circuits and 5 percent for feeders and branch circuits combined, with the ability to calculate wire size based on the AWG. The developer replied back and said it was a great idea. A few updates later, there it is! A full functional voltage drop calculator along with all the other Electrical and Electronics calculators. I got other Electrical calculators prior to this one, but after getting this one….none of the others matter anymore. This has everything. If you have any other ideas, just email the developer, if it can be done, they will do it :-)

This is just what I needed for hobbyist electronics work. The ability to do unit conversions is great! Would like series/parallel resistances and capacitances to be added, maybe some other common formulas, but overall this is great!

Very useful and easy to use. This app is exactly what I was hoping it would be definately buy it if you're into electronics.

I got the app and couldn't get it to work as described so i told my husband about it and since we are in the same field he started messing around with it and has nothing but good things to say about it so i don't know i guess that's this are called reviews right?

Don't belive everything you read!<br/>This is In no way usefull for utility work!<br/>They who say so must be new to power. No 3 phase calcs. So you decide if all the reviews are honest. Obviously I wish I could get my money back. Being new to the APplication down loading world, buyer beware!
