16. the headlights get brighter as the engine is revved. technician a says this is caused by a high capacity battery. technician b says this is caused by a faulty voltage regulator. who is correct?\ntechnician a\ntechnician b\nboth a and b\nneither a or b
Answer
Answer:
B. Technician B
Explanation:
Step1: Understand headlight - brightness principle
Headlight brightness depends on voltage.
Step2: Analyze Technician A's statement
A high - capacity battery doesn't directly cause headlight brightness to change as engine is revved.
Step3: Analyze Technician B's statement
A faulty voltage regulator can't maintain stable voltage. As engine revs up, alternator output voltage may increase without proper regulation, making headlights brighter. So Technician B is correct.
