A 5mA electrical shock can result in what effect?

A 5mA electrical shock can lead to involuntary movement away from the source. This reflexive action occurs because the body's reaction to the electrical stimulus activates the muscles, prompting an automatic withdrawal from the shocking source. The involuntary movement is part of the body's natural defense mechanism against electrical hazards, which aims to reduce further exposure to the source of shock.

In the context of electrical safety, understanding the effects of different levels of current is crucial. While stronger currents can indeed result in more severe consequences such as respiratory paralysis or heart fibrillation, a 5mA shock is generally not strong enough to cause those life-threatening conditions. Instead, the primary effect at that level is the body's immediate response to pull away from the source of the shock.
