Question

Technician A says that a component may be grounded through its mounting to a major metal part. Technician B says that some components must be grounded by connecting its positive terminal to a metal frame

Answer 1

Answer:

Technician B is correct

Explanation:

Grounding of component can be done by either connecting its positive  terminal  to a metal frame and then connecting its negative wire to the ground  and not  by mounting it on a major metal part hence Technician B is correct while Technician B is incorrect .

Electrical grounding is an alternate route created to allow excess current entering an equipment to go the ground without destroying the component
