Question

Quizplus · Accepted Answer

Technician A is correct because using a higher voltage allows for the same power to be transmitted with less current, which means that smaller gauge wires can be used. Technician B is incorrect because, while a 42-volt system is more powerful than the traditional 12-volt systems found in most cars, it is still considered low voltage and is not generally capable of delivering a lethal shock under normal conditions.
