How to measure internal resistance of a battery
The internal resistance of a battery is defined using two techniques: direct current (DC) by measuring the voltage drop at a given current, and alternating current (AC) (AC). When evaluating a responsive device, such as a battery, the researchers switch back and forth between the DC and AC test procedures, although neither reading is correct or incorrect.
