Question

technician a says a 12 volt automotive batteries have six cells connected in parallel. technician b says many diesel applications use two 12 volt batteries, connected in parallel. who is correct?

both technician a and b

neither technician a nor b

technician a only

technician b only

Explanation:

• Technician A: A 12 - volt automotive battery has six cells connected in series (each cell is approximately 2 volts, and \(2\times6 = 12\) volts). So Technician A is wrong.
• Technician B: Many diesel applications use two 12 - volt batteries connected in parallel. Connecting in parallel increases the amp - hour capacity (useful for high - current draw starting in diesel engines with high - compression ratios), while keeping the voltage at 12 volts. So Technician B is correct.

Answer:

Technician B only
