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:

Great App for Vapers as well 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.
