Question

Technician A says that almost every part of a vehicle is somehow powered by or controlled by an electrical or electronic system. Technician B says that in most automobiles, the battery voltage required to run the electrical systems is approximately 12.6 volts. Who is right?

Answer 1

I believe that both tech A and B are right.

Answer 2

Technician A and Technician B are both right

Step-by-step explanation:

Most modern day vehicles are mostly electrical cars meaning most parts of the car is controlled by electrical switches and buttons. the windows,A.c system, power steering , the radio/CD systems and even the opening of the boots and doors of the vehicle are controlled by Electrical systems installed by the Auto-Electricians while building/assembling of the vehicles.

The battery voltage required to run these various electrical systems attached to every part of the vehicles/automobiles are very minimal due to the modernization of electrical systems to consume very minimal voltages hence 12.6 volts can power/run the electrical systems hence technician B is also correct
