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 1). Figure 0.01 ΩΣ + 12 V 050 ΩΣ Jumpers Good battery 8V Dead battery 1 of 1 > 0.05 ΩΣ Starter motor ▼ Part A How much current could the good battery alone drive through the starter motor? Express your answer with the appropriate units. I = Part B Submit Request Answer μА I= Value Submit How much current is the dead battery alone able to drive through the starter motor? Express your answer with the appropriate units. μA Value Units Request Answer ? Units ?
