Ohm Calculator: Ohm's Law

Ohm Calculator solves Ohm's law in seconds. Enter any two values and get the other two: voltage (V), current (I), resistance (R) and power (P). Made for electronics students, electricians, makers and hobbyists who need a quick answer on the bench, in class or on site. WHAT YOU CAN DO • Calculate V, I, R and P from any two known values • See the result full screen, with the formula behind it • Follow a simple circuit diagram that matches your inputs • Keep a history of your calculations on your device • Read the built-in reference for Ohm's law and the power formulas • Use the short guided tutorial the first time you open the app MADE TO BE COMFORTABLE • Fast to open, easy to read, big touch targets • Choose from several colour themes and fonts • Adjust text size and the number of decimal places • Available in 12 languages, including English, Hindi, Spanish, Portuguese, French, German, Italian, Russian, Chinese, Japanese, Korean and Arabic • No account and no sign-up REMOVE ADS The app is free with ads.
