(a)A car has a fresh storage battery of emf 12V and internal resistance 5.0×10−2Ω. If the starter motor draws a current of 90A, what is the terminal voltage of the battery when the starter is on? (b) After long use, the internal resistance of the storage battery increase to 500Ω. What maximum current can be drawn from the battery? Assume the emf of the battery to remain unchanged. (c) If the discharged battery is charged by an external emf source, is the terminal voltage of the battery during charging greater or less than its emf 12V?
