Final answer:
The fraction of the battery's power dissipated by the internal resistance can be determined using a simple formula: Power = (Internal Resistance / Total Resistance) * Battery's Power.
Step-by-step explanation:
The fraction of the battery's power dissipated by the internal resistance can be determined using a simple formula. The power dissipated by the internal resistance is given by the equation:
Power = (Internal resistance / Total resistance) * Battery's Power
For example, if the internal resistance is 0.2 ohms and the total resistance is 1 ohm, then the fraction of the battery's power dissipated by the internal resistance is (0.2 / 1) = 0.2 or 20%.
