Ohm's Law

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:

Perfect for Vapers! 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!

Elegant in its practicality. 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.
