What is associated with a current level of 1 mA?

A current level of 1 mA (milliampere) is associated with a slight electric shock that is generally felt but not painful. This level of current is low enough that it typically doesn't cause significant harm or painful sensations. When electrical currents are at this magnitude, individuals may experience a tingling sensation or a minor discomfort, but it is usually manageable and does not pose a serious risk to health.

In contrast, higher levels of current are known to produce more serious effects. For instance, currents above 10 mA can lead to painful shocks, while currents that are considerably higher can disrupt normal heart function or even cause ventricular fibrillation, which is a severe cardiac event. This differentiation in sensation and physiological effect is critical for understanding the risks associated with electrical exposure and helps inform safety practices when working with electrical systems.
