What could result from contacting 100-200 mA?

Contacting electrical currents in the range of 100-200 mA can indeed lead to severe physiological effects, particularly on the cardiovascular system, resulting in death from heart failure.

At this level of current, the electrical flow can disrupt normal heart rhythms, potentially causing ventricular fibrillation, a condition where the heart quivers instead of pumping effectively. This can result in an inability of the heart to supply blood to vital organs, leading to a rapid decline in health and possibly death if not treated immediately.

While lower currents can lead to minor shocks or fainting, it is the higher currents within this range that pose a significant risk of fatal incidents due to their direct impact on cardiac function. Additionally, while burns can occur due to electrical contact with high current flow, the immediate risk of cardiac arrest is a more critical concern at 100-200 mA.
