Technician A says that the voltage regulator on many current linehaul trucks is set for a maximum 13.8 volts.Technician B says that when voltage regulators are set at a voltage exceeding 14.0 volts,light bulb life is shortened.Who is correct?
A) Technician A only
B) Technician B only
C) Both A and B
D) Neither A nor B
Voltage Regulator
A device that maintains a constant voltage level to electrical equipment, protecting it from damage due to voltage fluctuations.
Linehaul Trucks
Trucks utilized for long-distance transportation of goods, usually between cities or over hundreds of miles, as part of the logistics chain.
Light Bulb Life
The expected operational lifespan of a light bulb, measured in hours, before it fails or significantly decreases in brightness.

Final Answer :
C
Explanation :
Technician A is correct because the voltage regulator in many trucks is indeed set around 13.8 volts to ensure the electrical system operates efficiently without overcharging the battery. Technician B is also correct because setting the voltage regulator above 14.0 volts can lead to excessive voltage in the electrical system, which can shorten the life of light bulbs by causing them to burn out faster.
