Final answer:
When touching a victim who is being shocked, you may experience loss of voluntary muscle control and the victim may experience sustained muscular contractions and a 'can't let go' effect. The severity of the effects of electrical shock depend on factors such as the amount of current, the path taken by the current, the duration of the shock, and the frequency of the current.
Step-by-step explanation:
The effects of an undesirable electric shock can vary in severity, ranging from a slight sensation at the point of contact to death. When touching a victim who is being shocked, you may experience loss of voluntary muscle control which can cause you to not be able to let go of the source of the current. Additionally, the victim may experience sustained muscular contractions and a 'can't let go' effect, where the muscles that close the fingers are stronger than those that open them, causing the hand to close involuntarily on the source of the shock.
