6) (15 Points) A typical AA size 1.5 V Energizer alkaline battery has an internal resistance of 0.2 ohms. We connect this battery to different loads (i.e. light bulb) with different resistances. What will be voltage across the load if it has a resistance of 1 kohms, 100 ohms, and 1 ohms? For which one of these cases the internal battery resistance is most significant? Compare the current-voltage (I-V) curve of this battery to that of an ideal 1.5 V...

A car battery has an emf of 12.0 V and an internal resistance of 0.20 Ω. While the car is running, the resistance of the rest of the car (the “load” resistance) is 1.00 Ω. What is the current through the battery? What is the terminal voltage of the battery? What is the power delivered to the rest of the car? What is the power dissipated as heat by the internal resistance of the battery?
