iPod Apps?

Just got the New iPod Touch. Neet little toy but not yet sure if it was worth the price.

Anyways. I have herd some mention apps for resitor values, ohms law, and other electronics tools. but I haven't been able to find any other than conversion tools and the appp store don't seem to have anything or I am just missing it.

Anyone have any links to some apps?

Ohms law: http://itunes.apple.com/us/app/ohms-law-calculator/id293357601?mt=8

Coles law: Taylor & Francis - Harnessing the Power of Knowledge

Doesn't look like an app Ian...

I finally found the Ohms Law free app, and the Resitor Calc app After doing some searching. iTunes isn't the most organized site out there. I fianally got them downloaded after the iPod decided to stay connected.

Now I am looking for one that will calculate the resistance needed in a LED circuit, anyone know of one?
EDIT
Never mind, found that one too.

This is the one I use. Free.

I bought this circuit simulator for iPod/iPad. Haven't used it in anger yet but it looks nice...
