Very confusing interface. Could never figure out how to find the voltage drop across 9.63k ohms with 1.392ma.

Simple fast calculations, if your checking amp load on your battery based on resistance and battery voltage it's extremely accurate

Simple straightforward all you need for basic Ohm Law Calculations, Although I remember Ohms Law I can use it quicker than my Calculator
