What is the primary factor in evaluating the potential severity of an electrical shock?

The primary factor in evaluating the potential severity of an electrical shock is the flow of current or amperage. This is because the severity of an electric shock is primarily determined by the amount of electricity that passes through the body, which is measured in amperes.

When current enters the human body, it can disrupt normal physiological functions, such as heart rhythm, and can even be lethal if the current is strong enough. Generally, lower voltages can still lead to dangerous currents if the resistance of the body is low, but it is the actual current that poses the risk.

While voltage does play a role in how much current can flow through a circuit, it is the current that directly impacts the body. Very low voltages can still be harmful if they produce a sufficient amount of current, highlighting the primacy of current flow in assessing shock severity. Factors like resistance and duration of exposure can influence the overall assessment, but they are secondary to the crucial aspect of current flow.
