Which device creates an electrically conductive path by joining metallic parts?

The device that creates an electrically conductive path by joining metallic parts is known as bonding. Bonding involves connecting two or more conductive objects together to ensure that they share the same electrical potential and mitigate the risk of electric shock or sparking due to differences in potential. This practice is crucial in preventing static discharge and ensuring safety in environments where flammable materials may be present.

Grounding, while similar, primarily involves connecting electrical systems to the earth to dissipate excess current, rather than directly connecting separate metallic parts. An arrestor serves the purpose of protecting circuits from voltage spikes, while a lanyard is a safety device used to secure tools or equipment, especially at heights. Understanding the role of bonding in electrical safety is vital, particularly in industries that deal with hazardous environments.
