A faint tingling sensation can be felt when the body experiences a current of how many milliamps?

A faint tingling sensation is typically felt when an electrical current of around 1 milliamp (mA) passes through the body. This level of current is generally regarded as the threshold for the perception of electrical sensations. At this current level, most individuals will start to feel a slight tingling, which can serve as an indicator of the presence of electrical energy.

Higher levels of current can lead to more pronounced sensations, and higher currents may result in painful sensations or even physiological effects such as muscular contractions or adverse health effects. However, at 1 milliamp, the sensation is still relatively mild and serves as an important consideration in electrical safety and awareness. Understanding these thresholds is crucial for recognizing the potential risks associated with electrical exposure in various environments, particularly in workplaces governed by OSHA regulations.
