What is necessary in order for electrical shock to occur?

• A. A break in electrical continuity
• B. A difference in electrical potential
• C. An increase in load
• D. A direct exposure to voltage

Answer: (B)

For an electrical shock to occur, there must be a difference in electrical potential, which means that there is a voltage difference between two points. This difference creates the driving force that causes current to flow through a path that may include a person's body. When a person comes into contact with two points at different potentials, it allows electrical current to pass through them, resulting in a shock. Understanding this is crucial because it emphasizes the need to maintain safe practices when working with or around electrical systems. For example, even if a person touches a conductor, if there is no potential difference (voltage) between the point of contact and the ground or another conductive surface, current will not flow, and therefore, a shock will not occur. This principle underlines the importance of ensuring proper grounding and maintaining equipment to minimize the risk of electrical shock in any work environment.
