Now let's try using a pack of AA batteries (1.2 V output voltage and 0.2 Ohm internal resistance each) to replace the lead-acid battery. In order to match the car lead-acid battery, first, 10 such AA batteries need to be connected in series to form a 12V cell, while 50 such cells need to be connected in parallel (as shown in picture above; the total of 500 AA batteries are used). Find the power that is supplied to the same "car starter" using this pack of AA batteries.

Question

Now let's try using a pack of AA batteries (1.2 V output voltage and 0.2 Ohm internal resistance each) to replace the lead-acid battery. In order to match the car lead-acid battery, first, 10 such AA batteries need to be connected in series to form a 12V cell, while 50 such cells need to be connected in parallel (as shown in picture above; the total of 500 AA batteries are used). Find the power that is supplied to the same "car starter" using this pack of AA batteries. (Hint: for the second question, you need to find the total voltage and the internal resistance of the whole pack; you also need to find the resistance of the "car starter"; this can be done using the data of the first part of this problem) 

The car lead-acid battery has generally 12 V output voltage, and its internal resistance is so small that can be neglected. When starting the engine, the current of 480 A is flowing from the battery
to supply the "car starter" (an electrical motor that starts the engine ). How much power does the "car starter" consume when starting the engine?
