electrical path between 2 or more points wherein current flows. This path has
low resistance, usually less than 5 ohms. The path is constructed with
metal parts, such as copper wire, contacts, terminations, splices, and mating contacts of connectors.
||A measure of the difficulty for electric current to pass through a connection.

meet the insulation resistance specification.

the result of a misplaced contact within a connector.
barrier is missing and only a small air gap keeps metal conductors from
shorting. The tester detects an electrical arc when high voltage is
applied between these poorly insulated connections.
