When a worker in an insulated basket makes contact with a line, where will the greatest voltage drop occur when there is a potential difference?

The greatest voltage drop occurring across the worker in an insulated basket is due to the fact that the worker is the point of contact with the energized line. When a worker comes into contact with a live conductor, they create a pathway for electrical current to flow, which leads to potential differences in voltage across different parts of the system.

In this scenario, the human body is much less conductive than the conductive materials making up the boom of the truck or the basket itself. Thus, the worker's body presents a higher resistance to the flow of electricity. As a result, a significant amount of voltage will drop across the worker rather than throughout other structures like the basket, the boom, or the ground. This is an essential concept to understand in electrical safety and isolation procedures, as it emphasizes the inherent risks involved when working around live electrical lines.
