When a conductor that is carrying current breaks or when a loose connection occurs, it is a series arcing fault because the current is trying to travel in its intended path.
Step-by-step explanation:
A conductor is an object which allows electric current to pass through it. Some of the conductors are human body, metal, aqueous solutions of salts and graphite.
The electrons present in the electrical conductors freely move through the material or object. Electric current is produced by applying voltage across the conductor. The conductors help in transition of light and heat from one source to another.
The flow of electricity between two or more conductors is known as arc fault.
