A shock ranging from 6mA to 30mA can lead to which consequence?

A shock in the range of 6mA to 30mA primarily affects muscular control. In this range, an electrical shock can cause involuntary muscle contractions and a loss of muscular control, making it difficult for the person to release the source of the shock. This phenomenon occurs because the electrical current interferes with the normal function of the nervous system, which communicates signals to the muscles.

While other consequences can occur with electrical shocks, such as severe burns, cardiac arrest, and involuntary muscle spasms, those conditions typically relate to higher current levels or different mechanisms of injury. For example, cardiac arrest is more commonly associated with higher currents that can disrupt the heart's electrical signals. Involuntary muscle spasms can also occur but are not the primary concern in this specific current range. Hence, loss of muscular control is the most direct consequence of experiencing a shock in this 6mA to 30mA range.
