Which of the following factors most influences the severity of electrical shock?

The severity of electrical shock is primarily influenced by the interaction of voltage, current, and resistance. Voltage is the force that pushes electric current through a conductor, while current is the actual flow of electricity that can cause harm to the human body. Resistance refers to the opposition to the flow of current; it can vary significantly depending on the circumstances, such as the condition of the skin (whether it is wet or dry).

When voltage increases, it can push more current through the body, assuming the resistance remains constant. Similarly, if resistance is lowered (for example, through moisture on the skin), more current can pass through. It is the amount of current flowing through the body that primarily determines the severity of an electrical shock; greater current can lead to more serious injuries, including burns, muscle contractions, and even cardiac arrest. Considering these factors together gives a comprehensive understanding of how electrical shocks can vary in severity.
