Under which condition would a person most likely experience an electrical shock?

A person is most likely to experience an electrical shock when they become part of an electrical circuit because electrical shock occurs when a current passes through the body. This situation typically arises when there is a conductive path between a live electrical source and a person, allowing electricity to flow through the body to the ground or another conductive surface.

In this scenario, if a person touches an energized wire, equipment with exposed parts, or another conductive object connected to an electrical source, they can complete the circuit, resulting in an electrical shock. The risk of electric shock is significantly higher in environments where moisture or conductive materials are present, as these can facilitate the flow of electricity.

In contrast, touching a plastic surface typically does not conduct electricity, insulating the individual from a potential electrical hazard. Being insulated from the ground also reduces the likelihood of electrocution since it prevents the path for electric current to flow through the body to the ground. Furthermore, wearing rubber gloves provides additional insulation against electrocution, especially when handling electrical equipment, thereby reducing the risk of shock.
