The performance of the starter circuit in a car can be signif- icantly degraded by a small amount of corrosion on a battery terminal. Figure 19–91a depicts a properly functioning circuit with a battery (12.5-V emf, 0.02-N internal resistance) attached via corrosion-free cables to a starter motor of resistance Rs = 0.15 N. Sometime later, corrosion between a battery terminal and a starter cable introduces an extra series resistance of only Rc = 0.10 N into the circuit as suggested in Fig. 19–91b. Let P, be the power delivered to E=12.5 V S r= 0.02 2 the starter in the circuit free of corrosion, and let P be the power delivered to the circuit (a) with corrosion. Determine Rs = 0.15 2 the ratio P/P,. Rc =0.10 2 E= 12.5 V S r= 0.02 2 FIGURE 19-91 Rs=0.15 2 Problem 94. (b)
