An arcing fault current between conductive parts with an associated resistance is characterized by which of the following?

Explanation:
An arcing fault current is defined by current that jumps across a gap between conductive parts through ionized air, forming a plasma path. This arc provides resistance and heat, so it is not a zero‑resistance short; the current is carried across air rather than through a solid, perfect conductor. Arcs can occur in both AC and DC systems, and they’re not limited to copper conductors. That’s why the description of a jump with a path through air best fits arcing faults.
