Question

technician a says that when you jump - start a vehicle, a spark typically occurs when making the last jumper cable connection. technician b says that all four of the jumper cable connections should be made at the battery terminals. who is correct?

a. technician a
b. technician b
c. both technician a and technician b
d. neither technician a nor technician b

Explanation:

When jump - starting a vehicle, a spark often occurs when making the last jumper cable connection due to the sudden flow of electrical current. And it is not correct that all four jumper cable connections should be made at the battery terminals. The final negative connection is usually made to a grounded metal part away from the battery to avoid sparking near the battery which could ignite hydrogen gas. So Technician A is correct and Technician B is incorrect.

Answer:

A. Technician A
