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:

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

Used to love it 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.
