What effect is associated with exposure to 100 mA of current?

Exposure to 100 mA of current is particularly dangerous because it can lead to ventricular fibrillation and potentially cause the heart to stop. When an electrical current passes through the body, it can disrupt the normal electrical signals that regulate heart rhythm. At this level of current, the effect on the heart is severe; it can cause the heart muscles to contract inappropriately, leading to chaotic heart rhythms or stopping completely. This is why currents above 30 mA are considered particularly hazardous, as they can significantly impact cardiac function.

Understanding this effect is crucial for safety practices, emphasizing the importance of proper safety measures when working with electrical systems to prevent dangerous exposure. Other effects, while potentially serious at lower levels (like slight tingling, muscle contractions, or burns), are not as immediately life-threatening as the risks associated with ventricular fibrillation at 100 mA.
