How many milliamps of electric current will the human body feel electric shock when it is connected to alternating current?

The threshold at which the human body begins to feel an electric shock from alternating current (AC) is generally around 1 milliamp (mA). At this level, individuals may experience a sensation of tingling or mild discomfort. This sensation can vary based on several factors, including body resistance, the specific frequency of the AC, and the path the current takes through the body.

When current levels rise above this threshold to 10 mA, the sensation can become more intense, leading to involuntary muscle contractions. As the current continues to increase, serious injuries or fatalities can occur. Therefore, understanding the significance of 1 mA is crucial for recognizing safe levels of electrical exposure and the potential hazards of higher currents.
