4.) A switch that has failed a continuity test with an infinite ("OL") ohmmeter reading:
OA. has an internal short.
OB. is electrically good.
OC. is electrically open.
OD. has a short to ground.



Answer :

Final answer:

In physics, when a switch fails a continuity test with an infinite reading, it signifies an electrically open circuit causing zero current flow.


Explanation:

An open circuit refers to the absence of a termination, implying an infinite resistance resulting in zero current flow.

When a switch fails a continuity test with an infinite ohmmeter reading, it indicates that the switch is electrically open (OC).

This situation is similar to disconnecting a power supply from a circuit, creating an open circuit condition.
