What is the maximum amount of current (in AMPs) that can cause heart fibrillations?

The maximum amount of current that can cause heart fibrillations is typically around 1/10th of an ampere, or 100 milliamps. This level of current can interfere with the heart's electrical signals and potentially lead to deadly heart conditions like fibrillation. At this threshold, the heart may no longer effectively pump blood, as the electrical signals controlling its rhythm are disrupted.

Understanding the danger associated with varying levels of current is critical in the field of electrical work, especially for those who work with or around live electrical systems. That is why knowing the specific threshold for fibrillation is essential for safely assessing risks and taking preventive measures when working in environments where electrical exposure is a possibility.

In contrast, currents above this level can lead to severe injuries, but the primary concern related to fibrillation remains at the 1/10th amp mark.
