Answer:
Technician A is correct.
Step-by-step explanation:
The amperage should be the same throughout. In an electric circuit, the current is ratio of the voltage and resistance:

and

where V = voltage and R =resistance
The potential difference between two points is given as the electromotive force, emf.
This is the force required to more electrons from one point to another.
In a similar sense, the current is the flow of charge from one point to another in a circuit. Thus, the current should be the same throughout.
Hence Technician A is correct.
