SUMMARY
The discussion focuses on calculating the loss volt and internal resistance of a battery when a current of 2A causes the terminal voltage to drop from 12V to 9V. The loss volt is determined to be 3V, calculated as the difference between the initial and final voltages. The internal resistance is calculated using the formula R = V/I, yielding a value of 1.5 ohms. The initial attempt to multiply the loss volt by the internal resistance was incorrect, as it resulted in units that do not correspond to voltage.
