Please answer g 3. Your friend's car battery is dead and he calls you to come give him a boost. On the drive over, youthink about the electrical circuit required to jump start a car. See the figure below with two identicalcars: one has a charged battery with an EMF of 13 V that delivers a maximum current of 433 A (whenthe battery terminals are short circuited) and the other has a dead battery with an EMF of 12 V thatdelivers a maximum current of 120 A (when the battery terminals are short circuited).starterwwkey in ignitionchargedbatteryjumper cablesdeadbatteryjumper cableswwkey in ignitionstartera. What are the internal resistances of the charged battery and the dead battery?b. What is the resistance of the engine starter in the car with the charged battery if it draws 100 Awhen the key is turned in the ignition?wwc. How much current is drawn by the starter in the car with the dead battery? If it requires 100 A tostart the engine, does it draw enough current?d. In order to jump start the car with the dead battery, the charged battery is hooked up in parallelwith the dead battery using jumper cables. What is the charging current into the dead battery(without turning the key in the ignition)?e. What would the charging current be if you hooked up your jumper cables backwards, such that thebatteries were in series? What do you think might physically happen?f. If the batteries are hooked up in parallel, and the key is turned in the ignition of the car with thedead battery, find the current through the starter and through each battery.g. How much power is each battery supplying? How much power is the engine starter using?
