While having a discussion, Technician A says that voltage will be closer to 14.4 to 14.8 volts when the system is very cold and closer to 13.5 volts when the system is hot. Technician B says that voltage is closer to 13.5 volts when the system is very cold and closer to 15.5 volts when the system is hot. Who is correct?
A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question

Quizplus · Accepted Answer

Technician A is correct because charging systems in vehicles adjust the charging voltage based on temperature. When it's cold, the system increases the voltage to ensure the battery charges efficiently, often around 14.4 to 14.8 volts. When it's hot, the system reduces the voltage to prevent overcharging, typically around 13.5 volts. Technician B's statement is incorrect as it suggests the opposite of how temperature affects charging voltage.
