Which statement is true regarding injury risk with stun devices?

• A. High voltage will injure a subject regardless of current.
• B. The current does not affect injury risk.
• C. Current is the only determinant; voltage has no effect.
• D. High voltage won't injure a subject if the current is low.

Answer: (D)

Injury risk from stun devices is governed by the current that actually passes through the body. Voltage provides the potential to push current, but the amount of current that flows depends on the body's resistance and how long the current lasts. Stun devices are designed to deliver high voltage while limiting current, so even though the voltage can be very high, the current can remain low. When the current is low, the risk of injury is minimal, which is why the statement that a high voltage won’t injure a subject if the current is low is the best description. Other ideas that suggest voltage alone determines injury or that current has no effect miss the key point: current is what causes effects in the body, and voltage influences how much current can flow, depending on resistance and exposure duration. The true relationship emphasizes that current is the decisive factor, while voltage affects the potential for current to occur.
