Your truck’s battery dies while driving through the middle

QUESTION

Need Complete formula or Expression for this question:Your truck’s battery dies while driving through the middle of the desert, leaving you standed in the middle of nowhere. Fortunately, you notice that you have cellular service on your phone, but your phone’s battery is almost dead, making it impossible to call for help, and you only have a car charger that converts 12 V DC to 5 V DC. However, you also happen to have a small 2000 W gas powered generator in the bed of the truck that only outputs 120 V AC, some tools, and an old alternator. You decide to pull the alternator apart and find a rectifier circuit, a length l of insulated copper wire, and an iron ring whose outer diameter and inner diameter differ by 2s, and has thickness d after unwinding the alternator’s stator. You set out to make a transformer from the copper wire and iron ring by wrapping two coils around apposing sections of the ring. This transformer must convert the 120 VAC output from the generator to 5 VAC, which is then converted to 5 VDC by the rectifier.Part A – Using the maximum amount of wire for the coils, how many turns will your primary coil have.
