Final answer:
AC current can cause involuntary muscular contractions, leading to either being thrown away or being unable to let go of the conductive source. This muscular contraction makes it difficult to release grip, not due to the current being 'attractive' but because of the muscles' response to electrical stimulation.
Step-by-step explanation:
The effect of alternating current (AC) on the human body can vary, but it is typically not described as 'attractive' in the literal sense. When a person comes into contact with an AC source, such as a wall socket, the current can cause the muscles to contract. According to the descriptions found in various figures (e.g., Figure 20.27), the victim can experience involuntary muscle contractions, which can either result in being 'thrown' away due to an extension of the legs and torso or result in not being able to let go of the conductive object due to the muscles that close the fingers being stronger than those that open them.
The phenomenon of sticking to the socket is related to the latter effect: muscle contraction in the hand forces the fingers to grip tightly and makes it difficult for the person to release their grip. It is not because the current is inherently attractive but because of the way the muscles respond to electrical stimulation. Nevertheless, the risk of electric shock from AC is significant, and precautions such as wearing insulating shoes can help prevent a pathway for current flow through the body.
