How is electrical shock defined?

Electrical shock is defined as an injury caused by the passage of electric current through the body. This definition encompasses the various responses the body can have when it comes into contact with electricity, ranging from mild sensations to severe injuries, including burns or even fatalities. The severity of the shock can depend on factors such as the magnitude of the current, the path it takes through the body, and the duration of exposure.

When a person experiences electrical shock, the current disrupts normal physiological processes, which may lead to muscle contractions, interference with heart rhythms, or damage to internal organs. Because the electric current interacts directly with the body's tissues, it is categorized specifically as an injury, distinguishing it from sensations or electrical faults, thus solidifying option B as the correct definition. Understanding this definition is crucial for electricians and those working with electrical systems, as it highlights the seriousness of electrical hazards and the potential for injury in their line of work.
