Check it out. A friend of mine made this (first app I think). It's 3D rendered, looks cool, and only uses commonly availabe resistor values. Handy! Tell him to add support for some filter circuits or just put his 3D frontend on an open source Spice engine or something.

Now we have cell phones designing electronic circuits?

 

Oh we're gonna have a lot of things in the near future

 

The theory behind a voltage divider is remarkably simple, why is an app necessary for that? The app looks nice though, I can see how it would be convienent, if you didn't want to use paper, to quicly get an answer.

 

Just get "electronics toolbox" app, i wont link it as not an advert, but its an awesome app for all thing electronic!
