Electric shock occurs when an electric current passes through the body, which can disrupt normal bodily functions. This can happen when a person comes into contact with a live electrical source, such as a power line or faulty appliance. The severity of the shock depends on factors like the current's strength, the path it takes through the body, and the duration of exposure. The effects of electric shock can range from mild sensations to severe injuries, including burns or cardiac arrest. Safety measures, such as using insulated tools and wearing protective gear, are essential to prevent electric shock in environments where electricity is present.
