What may be set up at the base of a pole if it contacts a live circuit and also contacts the ground?

A voltage gradient may be set up at the base of a pole that contacts a live circuit and also makes contact with the ground due to the presence of a differential in voltage levels. When a conductor becomes energized, the electrical potential can create a gradient that causes a difference in voltage from one point to another, particularly from the pole to the surface of the ground. This gradient can be dangerous, as it can lead to the risk of electric shock for anyone who might inadvertently come into contact with the pole or the surrounding areas.

The concept of a voltage gradient is essential in understanding how electricity behaves in the environment, particularly near grounded structures. It highlights the necessity for safety protocols when working with or near live circuits to prevent accidents and injuries.
