A 12 V car battery dies not so much because its voltage drops but because chemical reactions increase its internal resistance. A good battery connected with jumper cables can both start the engine and recharge the dead battery. Consider the automotive circuit of FIGURE P28.65. a. How much current could the good battery alone drive through the starter motor? b. How much current is the dead battery alone able to drive through the starter motor? c. With the jumper cables attached, how much current passes through the starter motor? d. With the jumper cables attached, how much current passes through the dead battery, and in which direction?
