Which of the following is a primary factor in the severity of electric shock?

The primary factor in the severity of electric shock is indeed the path of current. This is because the human body has varying levels of resistance depending on the path that the electric current takes through it. If the current traverses vital organs, such as the heart or brain, the consequences can be far more severe than if it travels through less critical areas.

When considering how electric shock affects the body, the magnitude of the current, the duration of exposure, and the route taken are crucial elements. A current that passes through the heart can disrupt its electrical activity, potentially leading to cardiac arrest, while a path along the skin may produce milder sensations. Thus, understanding the significance of the current's path is essential for assessing the potential hazards of electric shock.
