About Ohm's Law
Two common calculators for electronics/electrical use:
Ohm's law calculator/Watt's Law calculator: figures any 2 unknown values given 2 known values
Resistor calculators: figures bands given value or value given bands. For 3, 4, & 5 band resistors
* Preferences/lock functions allow values to either autorange to appropriate SI units or remain fixed
* Resistor calculator automatically determines 3, 4, or 5 band
* Clean, intuitive interface
*** To the few who have commented that it's "stupid" to have the "Rate" button where it is, please stop && think. You don't HAVE to rate it before using it, nor are you even being asked to. You will notice that there are 2 buttons. This is the "About" dialog that is shown the first time you run any new version or tap the "About" menu item. Please think before you speak. Thank you. ***
Paid app "Electrist" identifies EIA standard values, as well as adds many more calculations. See for yourself:

I loved this app when I lived off of the Northeast Corridor line. Moved to the north Jersey coast line and it lists all NEC trains as servicing my station, as well as trains that don't go all the way. It has been rendered entirely useless.

Most apps of this kind overdo the features included or attempt to pack as many mini apps within it as possible. This one does not. It's features are powerful for the one thing it's used for: Ohm's Law. When I need to quickly do that calculation, I don't find myself sifting through endless other included features or mini apps. Straight to the point with a powerful user interface. Good job guys.

Does everything you want and easy to use and doesn't need any special permissions when you install the app. Very useful thanks heaps.

Much easier to use this in a pinch than trying to calculate everything in my head. Must have for vapor enthusiasts too.

Creating a Hardware Abstraction Layer for a custom one off DAW that needed to be integrated with a top tier analog recording studio...this saved me days of rewriting the code to accommodate superfluous possible options... I matched the load perfectly because I had the tool to find them.

This app does exactly what ot says, which is calculating Ohm's Law. Great for making sure you don't overdraw the battery in your mechanical mod. Also, the very small file size is a huge plus!

Great App when you have to check how low you can go on your battery or want to know how many Amps your coil would let through. Would be great if it kept the last Numbers if you restart the app.

Great app for figuring watts to volts with a known resistance. I use it to set my e-cig wattage.
