Not sure what is being asked, or is this may help. The logical approach in electrical troubleshooting is: Isolate/test/verify/test the circuit[s].
The electrical circuit when turned on it is considered closed. By the same token when an electrical circuit is turned off the electrical circuit is considered open.
Electrical devices need an electrical circuit.
There are 1000s of pieces of electrical eq, you must be more specific. In general, you test for ground fault, and circuit integrity. These principles can be further broken down to the specific item you are working with.
It is a non-destructive test carried out on a coating, eg.rubberised waterproofing coating to concrete, where holes through the coating are detected by the formation of an electrical circuit where there is insufficient coating to resist the electrical charge.
Different countries have different regulations about electrical inspection.
