You and a group of friends are on a day trip to a nearby national park. After a fun-filled day of fishing and boating, you are ready to head back home when you find that your car battery is dead. Your friend offers to use his car's battery and jumper cables to charge yours. The connections are shown in the two diagrams below. The internal resistance of your car battery is r = 3.15 N, that of your friend's battery is r = 0.01 A, and that of the starter is r, = 0.07 n. The live battery has a voltage of 12.0 v and the dead battery in your car has a voltage of 10.0 V. What are the currents through the starter and the dead battery? (Enter your answer for I, to least one decimal place.) I= 150.0283142 0.563162286 Use your value for I, to find the current through the dead battery.
