What is the expected range of milli-amperes that can cause a tingling sensation on a 60-hertz AC circuit?

The range of milli-amperes that can cause a tingling sensation, especially in a 60-hertz AC circuit, is typically between 0.5 to 3 mA. This sensitivity varies from person to person, but within this range, many individuals will experience a noticeable tingling sensation when they are exposed to electrical currents.

At lower levels, such as 0.1 to 0.5 mA, it may not be sufficient to produce a perceptible sensation, as the threshold for feeling electrical current differs among individuals. The range above 3 mA can lead to more intense sensations and can also pose further risks, making it crucial to understand the significance of these milliamp levels in assessing the risk of electrical shock or injury. As such, the correct range captures a critical point where awareness and caution must be heightened around electrical safety practices.
