The threshold of pain begins to be felt at what current measurement?

The sensation of pain associated with electrical current typically begins to be felt at approximately 0.1 A (100 mA). At this level, the current can stimulate sensory nerves in the body, leading to a painful experience. This aligns with the understanding of human physiology and how our nervous system responds to electrical stimuli, where values exceeding this threshold can induce not only pain but also potentially harmful effects.

When current levels are below 0.1 A, such as 10 mA or 50 mA, the sensation may range from a mild tingling to a slight discomfort, but they are generally not perceived as painful. Therefore, while lower currents can certainly be felt and may cause minor discomfort, they do not reach the pain threshold that begins to be felt at the 0.1 A level. As the current approaches higher values, such as 150 mA, the risks of injury and severe consequences increase significantly, reinforcing the importance of recognizing the pain threshold to ensure safety around electrical sources.
