What condition can lead to severe injury from electric shock?

High voltage with low resistance is the condition that can lead to severe injury from electric shock. This is because high voltage creates a significant potential difference, which can cause a greater current to flow through the body, depending on the resistance of the body and the path the current takes.

When resistance is low, the body allows more electric current to pass through it, increasing the risk of internal injuries such as burns, cardiac arrest, and other life-threatening complications. The severity of an electric shock is heavily influenced by the combination of voltage and the path of the current, making high voltage in conjunction with low resistance particularly dangerous in causing severe injuries.

In contrast, conditions like low moisture in the environment or high body resistance tend to limit the amount of current that can flow, reducing the likelihood of severe injury. Similarly, a short duration of contact with electricity means that even if the voltage is high, the contact does not last long enough to cause significant harm. Thus, it is the combination of high voltage and low resistance that presents the greatest risk for severe injury from electric shock.
