Ohms Law Calc.

Ive had the app for a while now and its definitely come a long way and its looking great. I’m a journeyman electrician and the app has been very useful. The dev is also really great at responding to feedback and making improvements. Highly recommend, for less then a coffee its a great deal.

Best this since sliced bread.

This app is fine for basic current and power calculations an electric car driver may need to figure recharging times. They are free along with voltage and power calculations. But I needed more: voltage drop over a 50 foot Extention cord that the EV charger is connected to. For a few dollars more, that is available plus a whole host of other calculations. Then there is the conversion side, which I do not use. You get Field Strength, Electrical Potential and Resistance for free but must pay a dollar to unlock the rest. Whether EV driver or dabbling in electronics, this may be the app for which you have been looking.
