Technician a says that when a fuse has popped, it just needs to be replaced, since it performed its job. technician b says that when a fuse has blown, the circuit needs to be diagnosed because the fuse was probably not the problem.
who is correct?
a. technician a
b. technician b
c. both technician a and technician b
d. neither technician a nor technician b

B) Technician B

Explanation:

Technician B's statement is correct because when the bulb gets damaged, there are probable chances that the circuit needs to be diagnosed or repaired.

When the power overloads in the circuit or different voltage nodes of wires get interconnected with each other then, there is also chances of short circuit as well. So, that is why circuit needs to be repaired.

So, these might be the possible reasons for the bulb that get trip or fuses apart from the defect in the bulb itself.
