Question

Quizplus · Accepted Answer

The primary purpose of replacing 14-volt systems with 42-volt systems in vehicles is to provide more total wattage. This is necessary to accommodate the increasing electrical demands of modern vehicles, including advanced safety systems, infotainment, and electrically powered steering and braking systems. Higher voltage systems can deliver the same power with less current, which can reduce the size and weight of wiring and improve efficiency.
