A. The spacity battery.Technician B says this is caused by a faulty headlights get brighter as the engine is rewved. Technician A says this i the regulator.Who is correct? A. Technician A B. Technician B C. Both A and B D. Neither A or B

## Step 1<br />This problem is about understanding the functions of different parts of a car's electrical system. Technician A suggests that the headlights getting brighter as the engine is revved is due to a faulty voltage regulator. The voltage regulator is responsible for maintaining a constant voltage level in the car's electrical system. If it's faulty, it could cause the headlights to get brighter as the engine speed increases.<br /><br />## Step 2<br />Technician B, on the other hand, suggests that the headlights getting brighter as the engine is revved is due to a high capacity battery. This is not correct because the brightness of the headlights is not directly related to the capacity of the battery.<br /><br />## Step 3<br />Therefore, only Technician A is correct in this case.
